SBOP 4.1 System Copy

Hello all,

Currently I'm planning to copy SBOP BI 4.1 on MS SQL to new hardware with different host name.

Already checked the admin guide available with SMP, which indicates following

- Build system with restored database with same node and credential.FRS restore and then RDT.

- New installation - > restore database, modify SIA ->point to restore database, FRS restore and then RDT.

Please share which one will be the best option consider less error and input (I guess the first option).

Also for DR what is the best practice, Application or Infrastructure level.

Best Regards
