Moving tapes, generally damages them unless you are very careful, but it is not that simple ...
Presuming you have LTO tapes, though most are prone to this.
If the tapes are not kept streaming (running above a cerain speed, they keep stop /starting. This reduces the tension in the tae, and instead of the tape pack lying flat, some of the 'wraps' of tape protrude above the main 'pancake' (as it's known).
It the tape is then moved, the tape pack rattles around and can damage the edge of the tape, as it hits the inside of the cartidge.
To reduce this risk the tapes have to be packed correctly, a solid case with 'solid' shaped inserts is NOT suitable (but is very often what 'tape storage' firms use).
'Bubble wrap is ood, providing each tape is individually wrapped, as far as cases go - these are very good.

The inserts are a soft squidgy foam, and are attached into the case using velcro and are quite a lose fit - therefore providing excellent protection .
When I used to move tapes (though not many) we suffereded many cases of unreadable tapes. Switch to these cases 100% eliminated the problem.
The better solution (if possible) is to locate the library physically in a different location - therefore the data is 'automatically' offsite, and no tapes have to be moved, the tapes stay in the library - which is the safest place for them.
