Activate a lagged database copy by replaying all log files on Exchange 2013

Scenario 1: Activate a lagged database copy by replaying all log files.

Step1 :Identify the lagged copy which must be replayed.

Step 2: Suspend the lagged database copy.

Use the following command: Suspend-MailboxDatabaseCopy “databasename\servername”

Step3:Make a backup of the database and log files for this database copy and move the files to another location.

Step4: Resume the database copy.

Use the following command: Resume-MailboxDatabaseCopy “database\servername”

Step5: Activate the lagged copy.

Use the following command : Move-ActiveMailboxDatabase “databasename” -ActivateOnServer “servername” -SkipLagChecks

Step6:When all the logs have been replayed, the database copy will mount and becomes active

Step7:The replay lag interval value is still configured for this database copy, it will come into effect again when the active database is moved to another DAG member!
