Hi Magnus,

I can see how it can be confusing. Let's see if I can make some sense of it.

1. EPiServer Manager <- The Manager for CMS 4 sites
2. EPiServer CMS Manager <- The Manager for CMS 5 R1 sites
3. EPiServer Installation Manager <- The Manager for CMS 5 R2 sites
4. EPiServer Deployment Center <- Same as 3. but renamed.

Now for your highly hypothetical question

1. Use the EPiServer CMS Manager to upgrade to R1 SP2
2. Download EPiServer CMS R2 and run the Setup.exe file.
3. Use the EPiServer Installation Manager and run the upgrade script.
4. Download EPiServer CMS R2 SP1 and run the Setup.exe file
5. Use the now renamed EPiServer Deployment Center and run the upgrade script.

It may sound like a lot of work but really just some button clicks away. Hope I made it a bit more clear.

Do you have more sites running on the server?

Thanks a bunch for the info Petter!

Yes, we have a lot of EPiServer sites running on that server, with versions ranging from 4.61 to R2 SP1. That makes using the "EPiServer Installation Manager" hard I guess since it's already been upgraded to "EPiServer Deployment Center" (for installing R2 SP1 on antother site). It isn't possible to use Deployment Center for upgrading R1 SP2 to R2? Should I then uninstall Deployment Center (R2 SP1) and install Installation Manager (R2)?

Regards,
Magnus

Right then you will have all the managers you will need. Just upgrade the site to R1 SP2 with the EPiServer CMS Manager and then open the Deployment Center.In that you should see something like this if you expand the 5.2.375.7 (R2) folder you will find the upgrade script from R1 SP2. Then the last upgrade script will be under the 5.2.375.113 (R2SP1) folder.
