There are two services listed for the Central Management database role, one with identity "CentralManagementDatabase:" and the other with identity "CentralManagementDatabase:" I ran get-CsService and found one service referencing LYNC-BE2. Remove the dependencies before deleting the store. LYNC-BE1 can be removed, but when I try to remove LYNC-BE2 from Topology Builder, I get the error: I am now unable to remove LYNC-BE2 from the topology. I stopped the services on the Lync FE servers, removed the 2013 FE pool, and published the topology. I moved the central database store to the SQL instance I created the 2019 Enterprise FE pool and moved all the users over to it. The 2019 FE pool is using an instance on a SQL 2016 server (SKYPE-BE) for its back end.

We are using this for internal IM, conferencing, Our Lync 2013 pool used mirrored SQL 2008R2 servers for its back end (LYNC-BE1 and LYNC-BE2). I am trying to complete a migration from Lync 2013 Enterprise to Skype for Business Server 2019 Enterprise.
