2. On the primary site, change the Protection Domain state from Decoupled to Disabled 3 Enable the original primary site as remote site

C. 1. On the prima7 site,suspend replications

2.

On the remote site, deactivate the Protection Domain using ncli

3.

On the remote site, migrate the protection domain back to the primary site

D. 1 On the remote site, restore the snapshots from the Protection Domain

2. On the remote site, select the Protection Domain and migrate to the primary site
