Migrate mailboxes

[lferran]

The users for which the mailbox in the old server has to be migrated in the new server are:

Username (email old server)	Mailbox size	SVN user exists?	Name of SVN user (if different)	aliases	migrated?

Most users that had mailboxes on the old server were already migrated as SVN users to the new server. For some users, the name of the SVN user is different to the name of the mailbox.

4 mailbox owners were not migrated because they didn't match the criteria defined in #454. To make the migration of the mailbox possible we can still create SVN users for them.

As I understand it, in the old server:

• All old ousers had a SVN account
• Only some of them had EMAIL account, username of which could differ from the SVN account.

For the users that EMAIL account is different from the SVN account, we have 2 options when migrating:

1. Make the SVN usernames as the ones stored in the uniqueIdentifier field in LDAP. Then, by means of email forwarding, we can configure mailAlias such that the mailboxes that differed end up in the same unique mailbox per user.

2. Create 2 LDAP users: one with the SVN username that doesn't have a mailbox, and one with the EMAIL username (that doesn't have access to the SVN?)

Most probably, option 1 would break the migration of old mailboxes. So we go for option 2.

Old mailboxes reside under the user's home directory following the Maildir format. They can be just copied from the old server to the new one. The procedure is as follows:

1. Create new folders under /srv/vmail/ in the new server for each user mail address. For instance, create: /srv/vmail/landauf@…/Maildir/

2. Copy the mailbox files&folders from the old server to the new one inside the newly created folder. For instance, one could use the *scp* tool.

3. Remember to change the ownership of the copied folder:

   chown -R vmail:vmail landauf@orxonox.net/Maildir
