Site 1 , Server A and B (Production)
Site 2 ,Server C and D (Pre-production)
Site 1 is production and Mirroring is happening between A and B
i need to push data from site 1 to site 2 and then set up DB Mirroring from C to D for pre-production instances , i cant setup Log shipping and Mirroring for Pre-prod from A or B as i need Pre-prod C instance available for updates as well.
as of now i am thinking of weekly restore of production backups on pre-prod C instance and turn on Mirroring for D pre-prod instances ,any better solution with less admin. tasks?
