Hello.
We are upgrading our environment from SQL 2014 to SQL 2016.
We are doing this by adding a SQL 2016 server to the existing availability groups that consist on SQL 2014 servers and failing them over. Once the failover is complete the AG complains about to 2014 boxes which is expected. We then remove the old 2014 replica.
However, when we access the old 2014 replica we can still see the AG listed in "resolving" state. If you look at the AG on the new 2016 box it does not list to 2014 box.
If we delete the AG directly on the 2014 box it will delete the AG entirely (including on the 2016 box).
Has anyone else seen this behavior and if so, do you know how to get rid of the AG on the 2014 box. Sadly we have to keep the 2014 box as we do still have some other databases on it for the moment.
I have googled this and have not found any threads with this issue to date.
Thanks in advance.
