Has anyone been able to upgrade to 2015 R2 from 2013 SP2?
We currently have our PROD environment on 2013 SP2 and a DEV environment on 2013 R2 for test purposes. We wanted to jump up to 2015 R2 and skip 2013 R2 and 2015 all together for our PROD environment. Here's what we did:
1. Create a new company in the DEV environment (2013 R2) as a shell and then restored a backup of PROD over this company, yes this would basically step the company down from 2013 R2 to 2013 SP2.
2. Install 2015 R2 and upgrade all companies in the db.
This is where I ran into a lot of problems with the newly created company because it was still on 2013 SP2. Numerous workflow tables were not found, all WF....... tables, StoredProcs could not be created due to missing columns that pertained to Workflow Status and a few new tables in the POP module for requisitions like the POP10200, POP10210, POP30200, and the POP30210. Again basically all of these were newly added in 2013 R2 because of the added functionality that GP brought inside the application with Workflows.
From what I can tell, to get to 2015 R2 will require a 2-step upgrade, first to 2013 R2 and then to 2015 R2.
In case you were wondering, the company that was already on 2013 R2 upgraded without a problem to 2015 R2. All the literature I find states that you only need 2013 SP2 to upgrade directly to 2015 but nothing is mentioned about 2015 R2.
