Moving SQL server 2016 DB's from mirroring to HA We have Windows Server 2016 machines with SQL server 2016 standard edition. Currently mirroring is implemented and now are planning to move to HA with 1 listener for each DB. We have multiple DB's 

In few DB stored procedure we have call to other DB with hardcode name.

Once we move to HA with 1 listener for each DB, will this new configuration be any issue for me?
Since you are on standard edition - you will be using Basic Always On availability groups for a single database.

The only issue that I see is that you have to failover all the interrelated databases together (since your app has cross db calls e.g. joins, etc).

I don't see any other issues except the limitations highlighted here.
