Hi,

If you recover the bootsrap from server A (6.1.1) onto server B (7.2.1; server B has same host name and IP while server A is shut down) using the standard 'mmrecov' command then what happens to the previous media and resource databases on server B that existed prior?

It used to be that 'nsr.res' and 'nsrjb.res' were recovered as 'nsr.res.R' and 'nsrjb.res.R' so no automatic overwrite, but you'd then shut down the server, move the respective '.R' files into place as 'nsr.res' and 'nsrjb.res' to overwrite the old ones and then restart, so it was never a merge, always a manual overwrite. I assume, however, that even with 6.1.1 and earlier that during mmrecov the media database would always get overwritten and there was no merge, correct? Now that we have a /nsr/res/nsrdb under 7.2.1 what happens if you run mmrecov? Is there a merge of the recovered database with the one that exists on disk or just an overwrite?
