Hi all,I've been presented with the challenge of handing a migration from our current SQL 2012 Web (64 bit) edition (Windows Server 2012 R2) to our new 2014 Enterprise (64 bit) running an AlwaysOn Availability Group (Windows Server 2012 R2). The big caveat of the challenge is that it is to be "zero downtime". There are three relatively small DBs that need to move (~75GB, 8GB and 5GB).I was wondering if anyone else has been faced with a similar challenge?... and if so, how did they handle it?I was hoping to configure log shipping from the 2012 instance to both 2014 SQL server instances, but I imagine I'll have to tear down the AG in order to do this. Then after all logs are applied to both instances, rebuild the AG. Does this approach work in theory?... or am I underestimating the effort associated with this?Thanks in advance.
