Additional steps to removing the original domain?

[gallimore]

Hi

When I first installed zimbra (5.0.16 Community) the default domain was created based on the machine FQDN. I have subsequently created a new domain into which the user accounts have been imported. I would like to get rid of the original default by using the following procedure:

1. Move all accounts currently in the default domain to the new one (the admin user, spam user etc)
2. Delete the old wiki account
3. Assign the new wiki account to be the global documents account
4. Delete the original domain

My question is:

Is this sufficient or are there additional steps I would need to complete in order to keep other services (spam/ham etc) working correctly?

Thanks
Paul
