Updating users during Confluence migration

[James Wardle]

Hi,

I need to migrate some spaces from one Confluence (A) to Confluence (B). Both are cloud.

The pages in the space for Confluence (A) will reference people e.g. joe.bloggs@hello.com (as creator, or as a commenter, or tagged in etc).

In Confluence (B) that user will have a different account e.g joe.bloggs@goodbye.com

When the XML gets imported for that space into Confluence (B) obviously joe.bloggs@hello.com can't be found so references joe.bloggs@hello.com (unlicensed)

So my question is: how do I migrate the space over from A to B and amend joe.bloggs@hello.com to be joe.bloggs@goodbye.com. 

Thanks
