Zimbra Desktop 2 Storage Migration

These are unofficial notes on how the store for items in Zimbra Desktop 2 differs from that in Zimbra Desktop 1, designed to aid in migration.

The rationale behind this is:

  • Zimbra Desktop 2 requires a totally fresh setup; no migration path from ZD1 is provided
  • I am living in a country with slow and expensive bandwidth
  • Our mail server is in a country with fast and cheap bandwidth

So my plan is:

  • Install Zimbra Desktop 2 somewhere with fast and cheap bandwidth to our mail server
  • Set up the same accounts as on Zimbra Desktop 1
  • Use rsync to efficiently transfer the Zimbra Desktop 2 setup without having to retransmit all messages

Complications that mean the installations don't exactly match:

  • The file store uses different names for the same mail items
  • Zimbra Desktop 2 uses gzip for all mail items over (approximately) 150kb; Zimbra Desktop 1 doesn't
  • The gzip compression doesn't seem to exactly match that produced by the command-line gzip tool at any setting, so can't be synchronized directly like that
  • Zimbra Desktop 1 seems to store some strange items
