Use Test a Copy in Logged Image Access mode, let it reach Logged mode, then choose Direct Access, then from the Activities pane choose Further Actions and then select Failover.
User do a test copy(not test copy and failover or test copy and recover production) , and some real application data was written to the image when copy is testing, User want to keep the data and want this snapshot with writen data be failback to production copy.  What can I do in this situation? I think the first step is to direct access, then what is the next? is to delete the CG and recreate a new CG and swap the production and replication, and then failover the CG? or there are some other easier steps to fulfill the task.
what can I do when we decide to keep writes to a test copy
