Changing copy mode from Global Copy to Metro Mirror
You can change the copy mode from Global Copy to Metro Mirror with the mkpprc command;
This operation is called Go-to-sync. Depending on the amount of data to be sent to the target, it takes time until the pairs become full duplex
Change copy mode from Global Copy to Metro Mirror:

You can use the -suspend parameter with the mkpprc -type mmir command. If you
use this
parameter, the state of the pairs becomes suspended when the data
synchronization is
completed;

You can add the -wait parameter with the mkpprc command. With the -wait
parameter, the
mkpprc -type mmir -suspend command does not return to the
command prompt until the
pairs complete data synchronization and reach the
suspended state;
Note: If you do not specify the -wait parameter with the mkpprc -type mmir
-suspend command,
the mkpprc command does not wait for the data
synchronization. If you do not use
the -wait parameter, you must check the
completion of the synchronization with the lspprc
command.

Changing the copy mode from Metro Mirror to Global Copy
You cannot change the copy mode from the Metro Mirror to Global Copy
directly. In order to
do this, you must use the pausepprc command to suspend
the Metro Mirror pair first, and then
resume the pair in Global Copy mode
with the resumepprc -type gcp command;
Change copy mode from Metro Mirror to Global Copy:
