Hi all,
we want to move 5 RAC/2 nodes AIX 6.1 nodes from datacenter A to datacenter B with minimum downtime.
DC A :
- RAC 11.2.0.4
- ASM DG's with NORMAL redundancy (40TB for all DBs)
DC B:
- same but ASM DG's with EXTERNAL redundancy on VPLEX METRO
What are for you the best solutions to move DBs with minimum downtime ?
- RMAN COPY ==> downtime
- Dataguard/GODEL GATE ==> $$$$$
- DC A : recreate DG in EXTERNAL redundancy and then move (EMC repli) to DC B ==> downtime
Thanks in advance for your answers.
