Comment(by gregorio):

 Hi Denis,

 XO downgrades now. I guess we're the first :-) Cisco IOS downgrades and
 does it while still operating! so maybe we're second.

 Not sure how we do it or how much NAND space it costs but its a valuable
 feature.

 The question of different versions interacting e.g. 8.1.1 collaborating
 w/8.2.0 is unrelated. Question of quality is N/A, it is what it is.

 Is the issue with xapian libraries only? Are you saying we cannot use any
 older versions of any libraries from Fedora? We have to take everything in
 Fedora 9 as is?

 I'm not opposed to anything in particular, just want to understand.

 There may be another option which is much more work for us (Sugar work I
 think). That is to have an old version of the Journal, if you downgrade
 you lose any changes made on 8.2.0 but you get back what you had. Not sure
 about that one, need Tomeu to elaborate or correct me.

 give me choices and costs and we'll make a decision:

 Option 1 - Lose revert feature
 Engineering cost - 0 coders, test cost high

 Option 2 - Use Fedora 7 Xapian binaries
 Engineering cost - big long term if we need support, testers cost low,
 other?

 Option 3 - Downgrade but lose any new data.
 Engineering cost - medium short term, low long term, test cost medium

 Now that I think about it, xapian isn't the only downgrade issue is it? We
 can't downgrade the whole release from Fedora 9 to 7 can we?

 We could before because we were on Fedora 7 and just needed to change the
 Sugar scripts. Let me know the whole story then we'll deal with it as best
 we can. Adios revert safety net, adios backward compatibility of
 activities, ay caramba!

 Thanks,

 Greg S
