Migrate data from existing pure disk

Hi,

Since you seem to be in the good practice of performing catalog backups you could do the following.

Build a duplicate master server (and media server if its not all in one). Keep the same name as the current one but leave it in a workgroup so it doesn't conflict with current one. Control name resolution with hosts files.

Then you'll need to copy the D:\DEDUP folder to that server, restore the last catalog before you reverted back to the first setup. Then implement Marianne's suggestion of duplicating to Basic disk. Once that is done you can then move the images on Basic Disk to the original server and import.
