A Dozen Things to Check. Here we go again!
It seems that it was only yesterday we were talking about all the things you want to look out for when upgrading to SQL Server 2. Now, just two years since SQL Server 2. SQL Server 2. 01. Describes cumulative update package 5 for SQL Server 2014 SP1.And that means, of course, people will be thinking about upgrading to SQL Server 2. So I’ve put together a. While you can certainly click . A proper upgrade process involves detailed research, planning, and execution. Failing to prepare a proper upgrade process for your database server is likely to result in your end users seeing diminished performance after the upgrade is complete. Since your goal is to increase performance and stability as a result of the upgrade you can understand that your users are likely to be upset if things were to get worse! Since it can be a daunting task to put together everything you need in a pre- upgrade checklist, I. Including these items into your checklist is likely to help you avoid 9. Please note that these steps are specific for an upgrade to the database schema and data. They do not include anything regarding the upgrading or testing of an application that is going to be accessing the upgraded database. You will want to remember to test your application and not just assume it will work perfectly even after the database has been upgraded. I would also advise that you perform these steps in a non- production environment first because I often find that common sense isn’t so common after all. Also please note that this list is meant to serve as a guide. However, I always recommend doing a migration whenever possible as opposed to the in- place upgrades. Migrations (typically done by restoring a database backup from the current instance) just make me feel more comfortable should I need to troubleshoot issues later. I like knowing I started with a clean slate, but that’s just how I roll. You should do what works best for you. Using the SQL 2. 01. Upgrade Advisor. The. Much like a consultant, it doesn’t fix everything that is wrong, it merely advises you on what actions you should take when upgrading to SQL 2. The actions the UA recommends will come in two forms: those actions to be done prior to a migration, and those actions to be completed post- migration. The UA is really good at finding what I call the “stub- your- big- toe” things that need fixing prior to a migration. But it is not foolproof, it will not identify every last detail. You will need to play the role of an actual DBA when migrating to a new version. Many of the items below will help you to do just that. Reviewing the “breaking changes” section in the Books Online. Did you know that Microsoft? You should review them to the point that they are familiar to you. You don’t have to memorize them all, just be familiar with them so that if something odd happens you can think to yourself “? I would like to believe that the UA will alert you to many of these breaking changes but the truth is the UA is not as dynamic as the BOL. That means the BOL may have an entry or two that doesn’t make it into the UA checklist, and that is why you should review this section. Currently (as of this post in June of 2. SQL Server 2. 01. I believe this is simply because this BOL entry has yet to be updated, so check back on this page often and I am certain you will find content listed. They are definitely worth reviewing, and they are also things that the UA is likely to never report back to you about because they aren’t things that *will* break, but merely things that *could* break. Also worth noting is that the BOL appears to have two entries for behavioral changes, one for SQL Server features, and one specific for the database engine. Executing DBCC CHECKDB WITH DATA. For databases created prior to SQL 2. For databases created in SQL 2. DATA? What about that little feller? Do you want to assume that the DATA? Here’s a thought: just go run it yourself anyway. That way you know it is getting done. Executing DBCC UPDATEUSAGE command. While not as critical as the DATA. For SQL Server 2. SQL Server 2. 00. However, in SQL Server 2. BOL entry link lists this command as being applicable for databases created in SQL Server 2. That seems odd to me, since this command is valid for SQL Server 2. I’m not certain why the SQL Server 2. SQL Server 2. 00. I’d recommend you run this for SQL Server 2. SQL Server 2. 01. In fact, I see this message for a handful of SQL Server 2. I think that it’s usage is. Updating statistics. This one is not to be skipped and is simply a MUST for any migration or upgrade checklist: USEdb. I’m the type of person that would rather be safe than sorry and therefore would end up running something like this: USEdb? WITH FULLSCAN'; Bottom line: don’t forget to update the statistics after an upgrade. Failure to do so could result in your queries running slowly as you start your testing and may end up wasting your time while you try to troubleshoot the possible bottlenecks. With SQL Server 2. Cardinality Estimator (CE), and I’ll talk more about this later, but you are going to want to make certain your statistics are as accurate as possible before you begin any testing. So, take care of the stats now, and you don’t have to worry about it later. Refreshing your views using sp. And, in what may be a complete surprise to many, sometimes these views will go across a linked server as well. The point here is that your view may not be of data that is contained in just the. In what could be the most dramatic twist of all, sometimes these views are created using a SELECT * syntax. I know, I know? And when you have bad code on top of views that go to other databases (or views of views of views of whatever else some sadistic person built) you are going to want to. Most of the time it won. But there is that one chance where it will dramatically improve performance and your customer will be happy as a result. Taking backups. You’re a DBA. You should have taken one prior to the start of any upgrade or migration, and you had better take one right before you turn that database over to your end users. Also, you should save any output from the items listed here, as it could prove helpful should something go awry later. Upgrading your hardware. Microsoft lists the minimum requirements for installing SQL Server 2. However, those are the *minimums* there. Chances are if your servers don’t already meet those requirements then you aren’t looking to upgrade anytime soon anyway. But if you are upgrading, then it might be time to upgrade your. Heck, you may even consider going virtual (if you aren’t already), which will still require you to examine your hardware requirements. But here’s the real reason you will. Let’s say that you are thinking of upgrading to SQL Server 2. In- Memory OLTP Hekaton. I can’t find any MSDN article that states if there are minimum hardware requirements for Hekaton, but I did find this blog post from the SQL Server team. Considering there is a lot of shiny new things in SQL Server 2. Knowing the right upgrade path. For those folks running SQL Server 2. KNOW you still exist) you are not able to upgrade directly to SQL Server 2. You have two options to choose from when going from pre- SQL Server 2. The first option is to do an upgrade in place to SQL Server 2. SQL Server 2. 00. SQL Server 2. 00. R2. The second option is to do a backup (or even detach) your database and restore/attach to an instance running SQL Server 2. At that point you will be able to complete the upgrade to SQL 2. And like I said at the beginning, I prefer to do migrations rather than upgrades in place. It’s just a preference. For something like a SQL Server 2. I’d need to do a backup, restore it to an intermediary version (like SQL Server 2. R2), then do another backup and restore that to SQL Server 2. At that point you should run through this checklist before turning it over for testing. You need to manually set the compatibility level yourself. With SQL Server 2. Cardinality Estimator (CE). I delivered a session at Tech. Ed this year on the new CE, Jimmy May has a short summary blog post regarding the new CE, and there’s also. Part of this is knowing which compatibility level you are using. I’d recommend you update every database on the SQL Server 2. Take a few minutes and read the release notes. No, they aren’t as funny as the release notes for apps on your phone, but they can be useful for you to review anyway. It’s good to have as complete a picture as possible for the new version should something not work as expected, and there are details in the release notes you may not find elsewhere. Conclusion. Upgrades are a necessary part of any development lifecycle. The chances of having a successful upgrade increases along with the amount of planning and preparation you invest in building a proper upgrade process. If you are planning to upgrade to SQL 2. If you haven’t started building up your SQL 2. They will save you pain, I promise.
