I’ve posted this earlier in the HowTo forum, but I believe that I need some more help on this.

Two years ago I’ve created my website in English and Dutch in EE. Each site consists of four weblogs. Since half a year I have relationships between weblogs in the same language specified in custom fields. The number of relationships is > 1000. On top, I have also relationships between various languages (for links like ‘dutch version’).

Now, I want to use MSM for various reasons. The migration is the hard part. MSM allows me to duplicate weblogs so for the content part that seems fine. I would chose to pick the 4 English weblogs to duplicate. But I’m afraid my new weblogs in my new website will have relationships with weblogs in my old website. Check: is this true?

The problem would be solved I wouldn’t copy the weblogs but just move them to another site. I.e. make the site_id in all related database entries ‘2’ instead of ‘1’.

Any suggestion?

Erwin, what type of relationships are you using, and did you build these using any extensions or just EE?

‘Just’ EE relationships. Just between weblogs, not between a weblog and gallery entries, if that is what you mean…

To be specific
http://erwinvanlun.com consists of four weblogs and relations between between them
http://Mensmerk.nl consists of four weblogs and relations between between them
+ there are relationships between weblogs in those sites (namely: translation links).

Erwin, I’m just not sure what is supposed to happen. I’m going to escalate this to the development team.

ok, keep me posted!

Any news?

Not yet, they’ll be posted in this thread.

Yes, any duplicated weblogs will have their relationship data applied as well.  When you duplicate a weblog in another Site, EE does not duplicate the actual weblog data, it just maps the existing data to another site.  Both sites will then use the same information.  Because of that, I don’t see a way to duplicate a particular blog (and its data) to another Site without retaining its relationship.

so just to be sure: actually the weblogs are not duplicated (copied), but just remapped to another site? Would that imply that I could just shift weblogs hence and forth? Suppose I would like to integrate two sites again, that would probably be just as easy?

Generally speaking, yes, you can change the assignment ID in the database for a given weblog/site to control which site owns that blog.  That said, using parameters in your weblog tag you can show any combination of blogs at any site, so you might not need to remap anything.

Erwin, did Rick’s comments answer your question?
