How to massively modify RQ associations?

Hello,

I'm going to modify our RQ organisation in order to centralize several types of RQ in one project instead of multiple:

We have currently for each projects RQ project (stories....), RQ business (clients...), RQ functional (cartography...), RQ quality (iso9126) and RQ technical (webservices, external services, platforms....). 

But thanks to the cross-project associations ability, we would like to centralize all the types of RQ except project ones in only one Spira's project. 

In this regards, I'm going to use the "export to project" functionnality....but I also have to copy the associations.....and I'm wondering what is the best way to proceed:

I think I'll update the 'TST_ARTIFACT_LINK' table by changing the SOURCE_ARTIFACT_ID and DEST_ARTIFACT_ID from the old RQ id to the new ones thanks to a table of correspondence.

Could it be possible to do it faster and easier?

Regards
