Moving Database ???

Windows 7
digiKam 7
In my evergoing battle to get the tags feature to quit crashing, I migrated my database to a new SATA-connected SSD.
It chewed on the situation for quite a long time and then informed me that it had completed successfully.
In my original location, there are four separate files, digikam4, similarity, recognition, and thumbnails-digikam.
However, in the new location, there is only a single file, digikam4.
Is this normal ?
I have done this a few times before and am fairly certain that all files showed up in the new location.
Thanks for reading and all help is appreciated.
