INDD to IDML

Question

Hello,
we've received an Indesign file from a customer, which was created in CS5.5.
In the links, it is linked to another Indesign 5.5 file.
I'll call the original file INDD1 and the linked file INDD2
When we export INDD1 to IDML, that works fine, but when we open this file in a lower version, it trips up on relinking the INDD2 file with a lot of plugin errors.
Can we first export the INDD2 to IDML, relink to that IDML file in the INDD1 file, then export it to IDML to circumvent this? And more importantly, can we do the reverse later on, so back to INDD from these IDML files?
Kind regards,
Geert

If you want to open the file in CS5, all of the linked files must also be CS5 or earlier. I ran into this, myself, a few months ago, trying to backport a file for a cleint I had mistakenly created in the wrong version.
I don't recall for sure whether I had to relink converted files in CS5.5 before making the .idml, or if I was able to set, in my case CS4, not to check links on file open so that I could open the CS5.5 idml and then relink to previously converted versions of the the links. Either way, though, you have to convert ALL of the files used, it just a question of wheter you'll need to relink in CS5.5 or in CS5.
As far as going back to CS5.5, that's not a problem, but INDD2 will not reconvert to the new version on its own. If there are no changes to that file other than conversion you can simply relink to the old unconverted version when you move back.
