Successful Upgrade from 5.0.23 to 6.0.8

[hodd]

We have 2 MTA, 2 Mailstores, and 1 Master LDAP. Everything went very smoothly.

Not a happy camper that canonical addressing is gone though...

[mmorse]

Technically it's still there via CLI for the moment Bug 46248 - remove canonical address from ZAC was 6.0.7, but Bug 33722 - deprecate canonical address is not committed (if you'd like to follow the discussion as to possibly why it might be phased out or suggested options to enhance instead).

Cross reference: No more Canonical Address.. and now?

I read through the first bugzilla posting and from what I gather it's this command:

zmprov ma ${ZUID} +zimbraMailCanonicalAddress ${EMAIL}

what's the ZUID?

[mmorse]

zimbra user id is the long string hash for an account in ldap (zmprov ga user@domain.com | grep zimbraId) - or as just alluded to, you can just use the account name in the command:
zmprov modifyAccount user@domain.com argument value
