Library Compatibility between Endnote versions X1, X2, X3

Hi,

we use Endnote on several workstations and think of upgrading at least some of them (in order to get rid of some problems we can’t get fixed on that workstations). No we wonder whether it will be possible to use our libraries on different PCs after that, i.e. is the library format in X1 and X3 identical?

Best regards,

Bastian

What about compatibility between Endnote versions X5 and X7? Some of our team have X5 and some are upgrading to X7.  What problems can occur in sharing libraries between the two versions?
