Hello everyone,

A collection was accidentally deleted in our repository and we've restored 
it using an AIP (see this thread 
<https://groups.google.com/g/dspace-tech/c/uspAAoD9hK4/m/JsciwqDyAAAJ> for 
Part I of this adventure).

Tragically, when the collection was restored, new handles and internal ids 
seem to have been assigned to all the items.  As a result, DOIs assigned to 
the items no longer resolve and the statistics history for these items has 
disappeared.

Our systems analyst believes we can get back the old handles and related 
statistics using Force Replace 
mode: 
https://wiki.lyrasis.org/display/DSDOC7x/AIP+Backup+and+Restore#AIPBackupandRestore-ForceReplaceMode

However, we see this has a significant warning attached, a la 'because this 
mode actually destroys existing content in DSpace, it is potentially 
dangerous and may result in data loss!'  I assume we'd lose any 
modifications made to items since the creation of this AIP that are 
included in both this collection and a non-deleted collection.  Are there 
any other issues we need to be aware of in running this mode?

Crossposting to DSpace Slack.

Thanks,
Carolyn.
