We will be undergoing scheduled maintenance on May 20th, 2013 at 02:00 GMT.
When it comes time to install SQL Server 2012. You have some options and this is going to be a two part video and in Part 1 I'm going to cover part of the options and then we'll finish it up in Part 2. But when we're talking about Installation Options, especially what you're going to see on the exam, they are going to concentrate not on just new installations. Very easy to just put the installation media in, install SQL Server, answer all the appropriate questions, follow the Wizard. All that sort of thing. But what we're really talking about here is, making an installation happen where we have SQL Server already in place and we have data in databases in earlier versions. And so in Part 1 here, we're going to talking about the In-Place Upgrade and in part two, we'll pay a little closer attention to the Side-By-Side Migration. Now that's your two basic choices if you are trying to put SQL Server 2012 into an environment where you already have SQL Servers out there with previous versions. Now you can also install SQL Server onto the Server Core and depending on the various documentations that you look at, they will consider a Server Core installation kind of a third option. So that's why you'll always see Server Core show up. Also keep in mind this is probably something you'll see on the exam because Server Core installation shows up so often because Microsoft's extremely proud of it, SQL Server 2012 is the first time that they have supported a SQL Server installation on Server Core. Now an In-Place Upgrade is just exactly what it sounds like, we take an existing SQL Server and we simply choose to upgrade that particular SQL Server to SQL Server 2012. Now all that is going to happen is it's just like an overwrite, the binaries of the old SQL Server version are simply replaced by those of the New SQL Server 2012, this is coming off your installation media. SQL Server data is automatically converted from the previous version and the prior databases to SQL Server 2012. There is not data copying, there is nothing that has to be migrated, transferred, nothing is required in that area, it's all just kind of going to happen for you. So if it, In-Place Upgrade is that good, what versions can I do it on? Well you can perform an In-Place Upgrade on SQL Server 2005 Service Pack 4 or later. 2008 Service Pack 2, 2008 Release 2 Service Pack 1 and versions earlier than 2005 Service Pack 4 cannot be upgraded. Those will have to be a Side-By-Side Migration. But still you are taking a pretty long stretch there from 2005 to 2012. So we're reaching all the way back to 2005 Service Pack 4 to be able to do an upgrade. Now if upgrades are so cool, let's talk about the pros and cons, what could possibly go wrong. Right. Well first of all let's talk about the pros, what's good about the In-Place Upgrade? Well it's usually easier and generally, got to watch that word, generally it's less risky than a Side-By-Side Migration. Now you generally get a pretty fast upgrade of everything all at once. If you've got an old SQL Server 2008 or 2005 Service Pack 4 database and you want to get everything at once, do an In-Place Upgrade okay? No additional hardware is needed, you don't need another server, you just kind of kick it off, stand back and watch it happen. Probably the biggest pro is that your server and instance names do not change, they stay the same, we are just replacing those binaries. And what that means in English is you don't have to make any changes to any of your applications to have them point to the correct instance, to the correct SQL Server to continue working. Now here's the cons for this, here is what can go wrong. First of all kind of a small con, you have less granular control. Now depending on how many databases you have in your SQL Server, this could be an issue for you because the instance must be offline during the upgrade. Now this means you are going to have to schedule some down time, do at night, do it on the weekend, whatever but your SQL Server is going to be down and unavailable during the time that this upgrade is taking place. Also you got to be careful here, make sure you take this risk into consideration. If you have a disaster during an upgrade and you start to you know get all kind of weird, bizarre messages, you lose power or something goes horribly wrong, a disaster during an upgrade can become a complex time consuming issue. First of all, worst case scenario, you're going to have to just kind of wipe it clean, install your entire operating system from scratch. Then you are going to have to re-install SQL Server onto that operating system from scratch and then start to restore all your SQL Server data. And if you want to see an administrator get really nervous, start restoring all of your SQL Server data. Okay. So those are some big cons but I will tell you that generally the In-Place Upgrade is what's going to be treated as kind of the favorite son if you will. So just make sure on an In-Place Upgrade that you understand the pros and cons and watch for these on the exam. So I'm going to end Part 1 right here, join me in Part 2 and we'll talk about the Side-By-Side Migration a little bit.
