Historical notes relating to migration from Herald to Nexus

6. After Migration

If it works: IMAP connections continued as before, but it was sometimes necessary to re-subscribe to folders. Webmail users found a message pointing to the new Outlook Web Access (OWA) service when they attempted to connect to Herald Webmail.
The username.herald.ox.ac.uk IMAP connection address was remapped to the Nexus IMAP server. Connections were presented with an appropriate Herald certificate and could connect using the same credentials. We hoped this made the migration as seamless as possible to IMAP clients.
What Username/Password do I use?: The system uses the Oxford (WebAuth) username and password.
If it fails: Full service was restored on Herald and we investigated the reason for the failure. If the reason was fairly simple, such as quotes in a folder name, the user received an email informing them of the nature of the problem and pointing them at a web link to fix it.
