I would like to migrate a few independent user accounts from my current ZCS Network Edition v7 to a ZS Open Source v8 server.

First of all is this combination possible? I mean from the Network Edition to the open source edition?

Second, on the ZCS OS v8 server I am looking the Account Migration feature specifying as "Zimbra Collaboration Server" as mail server type, I then enter the LDAP credentials of that server but if I continue I have the feeling it will migrate ALL my mail accounts of a specific domain, I just want to migrate for example one single mail account of a specific domain. Is this possible with the account migration tool? If yes how?

Thanks and regards
