Yes but with the following caveats. If you open the library in VX.2.1 it will warn you that it is adding some properties - this is nothing to be concerned about. But, if you use re-use blocks then you should only use the 7.9.4 versions of the library tools because re-use blocks will be upgraded to the VX.2.1 version of the iCDB and will no longer work with 7.9.4 if you edit them in VX.2.1.
thanks for your fast replay. I don't use re-use blocks. So I can use my common library for both versions, without problems.
