Need to modify pool addresses for archive folder

I know ES1 has come to EOL / EOS but a customer is moving from an old ECS system to a new one on version 3.8, so they are keeping ES1 software to access historical data (no more processing).

Pool addrresses on ECS-CAS archive folders must be changed to match the DNS name entries for the new ECS-CAS pool on the new device. Now, ES1 does not allow editing the pool addresses from the SourceOne console.

I guess a registry in some ES1Activity table must be modified, I'd appreciate some advice on this if someone has gone through this situation before.

Thanks in advance
