I’m currently working on a Microsoft Dynamics CRM 4.0 upgrade to Dynamics CRM 2015 project. That is 3 versions upgrade (4.0 >> 2011 >> 2013 >> 2015). A lot of folks asked me should they upgrade to 2013 or 2015 given that 2015 was just released – November 2014. Unless there is something that only 2013 offers then I would go with 2015 in a HEART BEAT!
One thing to note during the upgrade process – the final upgrade to CRM 2015 requires the CRM 2013 organization to be updated with CRM 2013 Service Pack 1 otherwise you will receive the following message:
The above message originated from our Microsoft CRM 2015 Upgrade Test environment where we had imported the CRM 2013 Organization to it. I want to stress the importance of parallel upgrade test environments while keeping the CRM 4.0 Production environment intact.
