Updating external HandleIDs on imported items

[Richard Hayman]

Hi group,

I'm hoping to clarify what changes I need to cover ahead of a migration. 

Several years ago we imported works from another institution into our existing Dspace 3.x install. On import, these items retained their existing Handle prefix and item IDs.

• Our prefix = http://hdl.handle.net/11205/xxxxx.
• Example item in our repository = https://mruir.mtroyal.ca/xmlui/handle/1880/46703
  
• Original item we imported = http://hdl.handle.net/1880/46703 

There are ~50 items like this. We feel we update these items to use our Handle prefix. 

I understand that we can update the existing Handle prefixes for these items, then batch-update related metadata (e.g., dc.identifier.uri).

Is this is the best way to make this kind of change? Will there be any problems (now or in the future) from updating the Handle prefix but not the item ID? Any other changes we'd need to make as part of this?

Thanks in advance,

Richard
