The only thing you will encounter in doing is you might have to repeat
the process of bringing the images back into PSA SE because unlike the
Elements Family, it does not have the ability to move things.
I would suggest trying two things:
1. Begin by moving the images and then (AFTER YOU MOVE THE IMAGES) click
on File>Reconnect all files. The problem with this method is you have
reconnect EACH file separately. Not a very pleasant option.
2. (Recommended) If you are not worried about tagging as much, then
simply click on Get Photos>From Folder and then pick the External Drive.
It might force you to pick a certain folder, so I do recommend keeping
them in something like My Picture Ext so that it is easier for you, but
it will do it.
See you have not enough Tags/Albums and other Organizer things in your catalog, you can simply create new catalog and manage your pics for Hard-Drive only...
Even Tag hierarchy can be exported and imrrted into new catalog.
Reconnect can be used in case you don't want to create new catalog.
See Whenever you decide to move delete files from File-System, remeber that Catalog will not get to know about the changes you made.
Please get back in case you have some specific queries...

Thanks Jim & VJ for both your very helpful suggestions. Everything is working like a dream so far. Thanks again. Christina
Just to add to what has already been suggested, if you copy your files in the same structure as they were originally, it willl be rather easier for you to reconnect, i.e. if you manually reconnect one file, others will get reconnected automatically very fast.
