Ok,

 

Thanks Vincent, the best was to test it ! J (and it’s what you said)

 

So :

-          without “with history” option selected : local page history is overwritten, new page version is imported page current version (for example “1.16”, but without previous versions)

-          with “with history” option selected : local page history is overwritten, new page version is “1.1”

 

To facilitate migrations, I think the ideal option would be “add imported page version on top of local page version”, just as if importing an existing page would be a modification of this page.

This way, it would be possible very easily to:

-          compare page before and after .xar import

-          rollback a page to previous state (without having to reimport a previously exported .xar on top of it …)

 

What do you think ?
