Correct.
If you can think of any subtleties that I might want to address before the migration, I would be grateful to hear them.
What's going to happen is that a new set of volumes will appear in your archive. QRecall will most certainly detect that the volumes you are now capturing are not the one you were capturing. Everything will be captured anew (with data de-duplication), but you'll still get a new layer with every file appearing to be a new version, with no history.
Your old volumes are still in the archive, and will no longer be appended to. When browsing your files, you may have to navigate between volumes if the item you're looking for is before, or after, the transition.
If this is acceptable, you don't have to do anything. If, on the other hand, you'd prefer to have a single history for all of your documents, then you'll want to
combine the new volume with the old one.
You're most likely to want this with your user files partition. Navigate to the "owner" level of the archive. Select both the new user partition volume and the old user partition volume, and then choose
Archive > Combine Items.... The items in the old volume will be migrated to the new volume, and will appear in the history that precedes the new volume. The old volume will then be deleted.
