We upgraded the binaries for ARS 7.3.1 to 7.4.3 on our publisher host after breaking replication and demoting the pub.
On Launch of configuration manager - seeing the new DB names to be created, and clicking NEXT we get an error about an object not being set to a reference … or some such.
Not in the troubleshooting guide - and applying the appropriate hot fixes for 7.4.3 changed nothing.
