Hello,
I was wondering if there was a relatively easy/straightforward way to change the topology manager of a domain to a new one that already exists. I found this Changing Domain Connection Config which was similar, but not quite exactly what I was looking for. I also saw this Upgrade To a New Release — Daml SDK 2.10.1 documentation which does work, but that changes the entire sync domain rather than just the manager.
I did a test using sandbox where I spun up 2 different sandbox instances and opened a canton console (passing in a conf file with the remote-domains and remote-participants). I then ran the following commands:
participant1.domains.list_connected()
participant2.domains.list_connected()
participant1.domains.disconnect_all()
participant1.domains.list_connected()
participant1.domains.connect(domainAlias = "domain2", connection = "http://localhost:6869")
where domain2 was the name I had specified in the conf file. I got this error:
ERROR c.d.c.e.CommunityConsoleEnvironment - Request failed for participant1.
GrpcRequestRefusedByServer: FAILED_PRECONDITION/INCOMPATIBLE_UNIQUE_CONTRACT_KEYS_MODE(9,352ab3c3): Cannot connect to domain domain2 as the participant has UCK semantics enabled and has already been connected to other domains: local::1220709e5e2c...

Command ParticipantAdministration$domains$.connect invoked from cmd19.sc:1
com.digitalasset.canton.console.CommandFailure: Command execution failed.
which I found was due to this Contract Keys in Canton — Daml SDK 2.10.1 documentation
Is it possible to migrate just the topology manager to a new one without migrating the entire domain (or maybe just the manager and the mediator, keeping the old sequencers where they are) using a process similar to this? Thanks
