IMHO found it's hard to understand this browser behaviour on your article.
Really? Perhaps I better change it then. Here's the bit on transferring user racks from the Live 8 Library to the Live 9 Library. Which bit is not clear? Using your Live 8 Library, racks etc
This may change, but at the time of writing, here is what to do. You can specify the location of your Live 8 Library in Places. Also you can specify a User Library, and an installation folder for packs. Most people will want to retain the ability to use Live 8 separately for some time yet, for example if using software that's not adapted to Live 9 yet such as Isotonik 8 for DJs.
The Live 8 Folder in Places has been made read-only, so you shouldn't be able to make them unusable (by changing them in 9). However, personally I would advise that for now you save racks etc in 9 under a new name, eg "AUD 9", so as to be sure the original is untouched and can therefore still be used in Live 8. This also helps you identify which is for 8 and which is for 9. You may not want to bother, it's up to you. It's just me playing on the safe side. Basically you can use racks etc created in 8 in Live 9, but not the other way round.
So, you can load an old rack (eg AUD) from Places: Live8 Library, and save it with a new name. The new version should be located in Live 9's browser in the Instruments Category, under Instrument Racks, at the bottom of the list...
...and also in Places: User Library.
