Migrate accounts from 1 server to another

[oliware]

I want to migrate some accounts from 1 server to another, problem is that I don't have a lot of info from the old server, I just have root access on the machine.
When I try to do an export, I receive this:

/opt/zimbra/bin/zmmailbox -z -m oliver@xxxxx.be getRestURL “//fmt=tgz” > /tmp/account.tgz
Exception in thread "main" java.lang.IllegalArgumentException: Invalid uri 'https://backup.pffffft.com/home/oliver@xxxxxx.be/�%C2%80%C2%9C//fmt=tgz�%C2%80%C2%9D': escaped absolute path not valid

so something wrong with the quotes.

now I get this :

ERROR: service.FAILURE (system failure: GET failed, status=501 not implemented yet)

A version that is too old ?
