- https://bugzilla.zimbra.com/show_bug.cgi?id=49807

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
```

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:

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
