Hello,
I currently have a Project Server 2013 3-tier farm which is currently on September 2014 CU with SP1 installed. For a few development reasons I was not able to patch it further, but now I have to bring it to March 2016 CU.
For some reason the patch install fails stating "The expected version of this product was not found".
Here's what I have tried,
1. Tried installing previous CUs one by one and it finally accepted Feb 2015 CU.
2. After upgrading to Feb 2015, the install failed yet again and only March 2015 CU seemed allowed.
3. Post March 2015 CU update, its now allowing only April 2015 CU, even May 2015 CU fails giving the same error mentioned above.
Is there any pre-requisite that I am missing here? I would like to come up to March 2016 patch version of sharepoint without having to install updates or CUs for every month one-by-one.
Any help would be appreciated here.
