We have a client with a very basic system - GP, RM, PM, CM, Payroll (CDN) and using IM for external data import from custom application. Have been using the system since 1996 so this is a long time, well established client.
Situation
We are starting to work on their update to GP2015 and we have a completely separate UAT Environment for both the SQL Server and the Workstation.
To kick off the process the IT department cloned the current GP2013 Server and create new VM machine. They did the same for the testing workstation.
There are no access or operational issues with the UAT from the Server or from the UAT Workstation
There are two company databases
Issues Encountered
After confirming that the current version as cloned worked in the UAT, we dowloaded from Partnersouce the GP2015 RTM R2 DVD as well as the latest KB3066933 (June 25)
We installed the GP2015 and got version 14.00.0725
When we run Utilities we get a Problem with installation message and a refer to the UNINSTALL for more details.
Looking at the DUINSTALL in the GP2015 folder we find:
PROD 0 does not support update from 12.00.1920
PROD 1911 does not support upgrade from 12.00.21
PROD 7131 does not support upgrade from 12.00.1905
First Solution
Instllation of the KB3066933 which results in version 14.00.0778
When we run the Utilities we get the same errors, less the message for PROD 1911
So when this failed, I uninstalled ALL OF GP2015 and
Second Solution
Downloaded the original GP2015 RTM DVD that results in 14.00.0524
Completed the installation - all the same errors.
Third Solution
Download all the service packs and install and test
KB0300074 as SP14.0.619 - 2/15/15 - fails PROD 0, 414, 1911, 6499, 7131
KB3063038 as SP14.00.0725 - 5/29/15 - fails PROD 0, 1911, 7131
QUESTION
What am I missing? I can not think of anything else I have to do. I have been doing update for years and this is one that I dont get at all.
