Problem

After doing a Migration of ZCS using the NG Migration method accounts configured with MAPI, IMAP, POP protocol stops syncing with the existing profile.

Analysis

NG export import is designed in such a way that it only deals with user data and not the server side data namely Tokens. Tokens are the one that act as an index between server and MUA. When an index is broken the existing profile does not know from where to start the sync and as a result it fails.

User-Side Data

  • Emails and Attachments
  • Folders (local and shared)
  • Calendars
  • Documents (for 6.x exports)
  • Briefcases
  • Tasks
  • User Preferences


Server-side Data

  • COSs
  • LDAP user Configs (such as External Auth)
  • Domain Settings

Error Logs

We can get the below log pattern on mailbox.log when an sync request comes from an migrated existing ZCO profile

Solution

The only solution for this is to re create the profiles once again.

To avoid this we recommend to do Rsync method of migration, which will avoid re creating of profiles after migration. This wiki contains more information.
