Usage example:

zxsuite powerstore doMailboxMove mail2.example.com accounts john@example.com stages data,account
Move mailbox for account john@example.com to mail2.example.com host

Parameters

destinationHost: The host to which the mailbox will be moved

accounts: The mailboxes to be moved

domains: The domains to be moved (when a domain is entered, all mailboxes in that domain will be moved)

input_file: The absolute path to a file containing the list of mailboxes to move, one for each line

stages: Select which stages to execute

compress: Compress the moved data

checkDigest: Check BLOB digests during the moves

overwrite: Overwrite existing mailboxes

threads: Number of operational threads, raising the number of threads will make the operation faster and more I/O intensive

hsm: Apply HSM Policy for moved mailboxes

notifications: A list of additional email addresses to be notified of the operation, comma separated

ignore_partial: Ignore previous partial moves

drop_network_backup: Delete the mailbox's data from the Legacy Backup (Zimbra NE only)

read_error_threshold: Maximum amount of allowrd errors before the operation gets interrrupted

doMailboxMove Details

• When moving a domain, each account from current server is enumerated and moved sequentially.
• Mailbox is set into maintenance mode for a very short period of time when it’s moved, and will be placed into original state after all emails are moved (after the ldap stage).
• Operation is stopped if 5% or more write errors are encountered on items being moved. Pay attention that the current mailbox may remains in maintenance mode.
• Single-mailbox moves will not start if destination server has not enough space available or user just belongs to destination host.
• All data is moved at low-level and will not be changed except some small things like mailbox id.
• The operation is made up of 3 stages: blobs|backup|account.
  • blobs: all blobs are copied from source server to destination one.
  • backup: all backup entries are copied from source server to destination one.
  • account: all non-blob information are moved.

• All of the stages are executed sequentially. If a single stage is specified, mailbox is parked in maintenance mode though the entire operation. On success mailbox will be placed into original state.
• Initially all blob items will be stored into destination server primary volume.
• On the reindex stage’s completion an HSM new operation is submitted to destination server, if not specified otherwise.
• All volumes' compression options are taken in care. * The MailboxMove operation can be executed if and only if no others operations are running on the source server.
• The HSM option applies current HSM policies. It’s runs after each mailbox is successfully moved, on any run new items will be moved.

Data persistence after a move

Mailbox information and data is preserved in the source server for 30 days after the move, in order to purge all data belonging to moved mailboxes use the `doPurgeMailboxes` command:

Syntax:
   zxsuite powerstore doPurgeMailboxes {Mailbox id or "all" to delete all mailboxes moved more than 30 days ago} [attr1 value1 [attr2 value2...]]

PARAMETER LIST

NAME                   TYPE       EXPECTED VALUES                                                            
mailbox(M)             String     Mailbox id or "all" to delete all mailboxes moved more than 30 days ago    
ignore_retention(O)    Boolean    Also remove mailboxes moved in last 30 days                                

(M) == mandatory parameter, (O) == optional parameter

Usage example:

zxsuite powerstore doPurgeMailboxes all
Delete mailboxes moved more than 30 days ago
zxsuite powerstore doPurgeMailboxes all ignore_retention true
Delete every moved mailbox
