I'm trying to upgrade a 2015 on-prem installation to 2016. I'm using the same admin account to install as when I installed originally, same service accounts specified, etc...
When I get to the "System Checks" page, it checks off Operating System and Server User Input, and then moves onto CRM Database, where it just sits and does not progress. When I look in the logs, I can see it going through the Database check section, and the final lines are:
---------------------
13:24:09|Warning| Check SqlDefaultValueConstraintValidator : Warning: The default value constraints in the Microsoft Dynamics CRM database are not consistent with Microsoft Dynamics CRM default value constraints.
13:24:09|Verbose| Connecting to database Data Source=DBSVR01\DYNMSCRM;Initial Catalog=CAWST_MSCRM;Integrated Security=SSPI.
---------------------
And this is where it's just sitting. Server isn't crashed, no non-responding processes....just, nothing's happening. (Note: there are a few other db checks that happen before this, and it gets past those just fine.)
So I tried just upgrading the server without upgrading the org, and that worked fine. Then in the Deployment Manager I try just upgrading the org, and it hangs again. The crmdmsnapin log shows the exact same final lines as above before it just stops proceeding.
This org was created in CRM 2015, so not some old version that's been updated over and over, or anything like that. And we haven't touched the DB directly or done anything out of the ordinary with the organization or its config.
Any ideas as to what I can try next, or where else to look? Out of curiosity, has anyone done this successfully yet?
