Exchange SQL And IIS- P103:The following legacy Exchange features have been de-emphasized in Exchange Server 2007. What does that mean?

Following this method means that the active storage group copy will continue to have meaningful filenames that represent that they indeed are active production copies. Why is this the preferred method Because Microsoft believes that using the Restore-StorageGroupCopy CMDlet with the ReplaceLocations parameter could lead to future confusion in distinguishing the active copy of the data from the passive copy of the data and to be honest we agree. That said we cannot see why you shouldn t use the ReplaceLocations parameter if you know what you re doing just make sure that you switch back to the original disk set again. Let s examine an example of how you would use the recommend method. First make sure that the production database is dismounted. Then open the EMS and type Restore-StorageGroupCopy -Identity First Storage Group . This command will activate the copy and leave the path for the production storage group intact. Now you can choose between either moving the LCR copy files to the location of the original production database manually using Windows Explorer or using Xcopy or a similar tool.
