It sounds to me like you are attempt to copy an existing (production) system over onto your test server, but you are still "attached" to your existing test system. Do you still have agents running on the test server that were configured for the test server?
thx for your response. Both GW systems have no connections or are tied together in any circumstance. The testsystem is a complete new install with one test MTA/GWIA/POA with one local user (No LDAP). The production system is connected via LDAP to our eDir. Maybe thats a problem?
I did not any configuration in the admin console of production servers. In the Overview are no test POAs/MTA's listed. Is there another point where I could see if the admin consoles of prod. and test talk to each other? Do I have to separate them into different networks or is it enough to block the admin port between the servers. I will go forward an test this..
unfortunately blocking the network traffic from/to the production server changes nothing. Still getting the message "You cannot upgrade domains or post offices from a different system." I'm grateful for any ideas :)
more testing didn't end so well. I created a new PO in the test system and then pointed the folder to a path where I copied the production PO. Updated the settings in the Admin Console resulted in a POA that won't start with the message "ip/port already in use" Any other suggestion how I can migrate a POA with eDir/LDAP integration to a different GW system with non LDAP integration? Is it so hard to accomplish this?
