Proxy Component Option

Proxy component option:

• Install & Setup Proxy On Your Current ZCS Server
  • Most likely you'll want this on your current production box. You'll rerun the zcs installer so you can add the zimbra-proxy and memcache components -- if you already don't have them installed that is. This command will let you know what you had installed and what was enabled/disabled.

    • zmprov gs `zmhostname` | grep -i service

  • Proxy Section in the Admin Guide:

    • http://wiki.zimbra.com/index.php?title=Zimbra_Proxy_Guide
• Now Install The New Mailstore [ref: Install Guide]
  • Packages would be: zimbra-store, zimbra-apache, zimbra-spell, and memcache [should be on mailstores when proxy is being used].
    • Your current server most likely already is the 'logger host'.
  • Ref for install:
    • http://www.zimbra.com/docs/ne/latest/multi_server_install/multi-server_install.5.05.html
• Add one user to new mailstore, test access through proxy
• Use zmmailboxmove to move user's to new mailstore
  • Ref for zmmailboxmove:
    • CLI_zmmailboxmove_Network_Edition_only

Non-Proxy Component Option

Non-proxy component option:

• Install new mailstore [ref: Install Guide]
  • Packages would be: zimbra-store, zimbra-apache, zimbra-spell
    • Your current server already is 'logger host'.
• You'll set this variable on both servers :
  • To see current setting:

    •  zmprov gs `zmhostname` zimbraMailReferMode

  • To set option:

    • zmprov ms `zmhostname` zimbraMailReferMode wronghost

• Add one user to new mailstore, test access
• Use zmmailboxmove to move user's to new mailstore
  • Ref for zmmailboxmove:
    • CLI_zmmailboxmove_Network_Edition_only
