Had to change External Hard Drive; How do I make the change in DigiKam ?

Having looked at the database on Windows (the Windows 10 PC is from my
OH) and I think it should be a simple replace disk operation:
Copy all the data from your old drive where digikam is mounted eg. M:.
Rename the old drive to something else. e.g. M: becomes N:
Name the new drive as M:
As far as I can see the Windows version of digikam does not seem to use
drive specific identification, but does identify the drive number.
BUT:
If the above does not work then you are in for a bit of a puzzle, to get
this absolutely solved. Meaning that what I've read in the Windows
database DOES mark the disk specifically and you need to play games with
the database.
On Linux the disk IDs are used and any disks you swap have to be
re-identified. It may be that you can swap Linux disks as well, but as
you have said there is no documentation covering this . If you have
collections with loads of tags and references it would be a pity to lose
this on a disk swap-out.
I find this the weakest point of digikam and have resorted to using SQL
to deal with this in the past.
As a guide if the above does not work you will have to:
* make a copy of the current database (digikam4.db in the base
directory of your photo library).
* make a new virgin version of digikam on the new disk - do not add
anything except for setting the base directory for your library on
the new disk
* if you cannot make a new version you will have to temporarily remove
the current disk
* ** dump the AlbumRoots table from the new disk
* ** get the entry for the disk identifier
* ** change the entry in the AlbumRoots that identifies your current
disk for the identifier that has been created for the new disk
* delete the new installation of digikam from the new disk
* re-install the current disk if removed
* copy your library to the new disk
* restart digikam
It should pick up the new location
** What you need to have if you have to follow the above is to be
comfortable with the command line and SQL. You will need more than an
hour to do this at a comfortable pace.
I have done this a few times successfully. I took this action because as
you say there is no documentation and although I do not mind rebuilding
my library I do not want to have to rebuild all my tags. I use Linux and
Mac, and have migrated the database to MySQL, mainly because I wanted to
use other tools to access the database but that's another story.
Hope the simple solution works ;-)
Good luck
