How can access host consistent target copy

Hi

There is a CG on RPA ,and no need replication for this CG anymore. My plan is use target volumes of CG at DR site but also, ı want to sure the target volume are consistent. 

There is a option is test mode to check all target volumes. After checking all volumes consistecy, if I disable and remove CG during test mode, all volumes still will be consistent? 

Or do you have any suggestions to do this operation?
