New Replication member in wrong DR group

I recently added a very large (2TB) member to the wrong DR Grouo, is there any way to move this member to the correct DR Group without breaking replcation & recreating the member?

Re: New Replication member in wrong DR group

Hi David,
I believe that the answer is no.
FYI, I moved quite a few replicas over the summer and took notes on same. Some completed in less than 3 hours but others took as long as 38 hours! Performance can suffer. I think that vdisks with lots of free space and few updates will replicate quickly, however I did not have access to many of the hosts so did not always know how much space was used. We have 5xEVA8x00 all 2C16D.
It is recommended to have a 1:1 relationship between a vdisk and DR group.

Its not always correct to have a 1:1 relationshsip between vdisk and DR group. With databases for example it is important that both the logs and the database are in the same DR group, because the write order is maintained at the DR destination within a DR group but not acros DR groups.
