[xwiki-users] on XWD_ID

Hi, I've read this recent thread about how XWD_ID is generated... http://xwiki.markmail.org/thread/vp7iuwul4oepf5jx We do need to link a number of external databases containing information on a per user basis. Thus, we do need to add a property/field/independent variable to "remote" database tables to associate information store on that database and on XWiki (until we are able to store all, or at least most, of the information in a XWiki Schema!). Considering we are still running XWiki Enterprise 2.4.30451 and an update is a must here, if we use the current XWD_ID as "linker", once we update to a, let's say, 4.x XWiki release, could we transform IDs in remote database to the new values XWD_ID will have in newer XWiki releases? I'm not sure I'm explaining myself here. Even I'm not sure if it is correct to think that XWD_ID will change when we upgrade. Please, your insight will be extremely welcome! Thanks for your help.
