Create local Clone copy session VMAX3 200K

Hi,

Team I want to create local clone copy session between SRC & TGT devices. It is my first time to do this task.

1. # of SRC devices are 98 and RDF1+TDEV devices.

2. # of TGT devices are 98 and TDEV devices. 

3. after terminating the pairs the tgt devices will be in production and src devices will be deleted. 

4. Remote replication will be started from tgt devices to remote array.

Question is:

Q1: what is the best plan/steps to perform this cloning task.

Q2: is it safe to create clone pair between RDF enable devices with simple tdev devices.

Q3: total size of SG is 34TB. should i use -copy or -precopy while creation the pairs.

Q4: If i want to restore the session, what will be the steps.

Thanks
