Hi Eric, with the release of vWorkspace 8.5, only vWorkspace licenses but no longer legacy WSM licenses are issued. WSM 7.2 can import legacy WSM licenses (.txt) and vWorkspace license files (.asc). You can't Import WSM license files (.txt) into vWorkspace. However, if you purchase vWorkspace Permier Edition per Access Device, you can use the license in WSM and also vWorkspace, because it is now one product. 
vWorkspace 7.2 looks like it accepts both WSM and vWorkspace licenses.  Is that the last version that is compatible with the WSM licenses or do WSM licenses work in the 8.0 and 8.5 space? Thanks!   
What versions vWorkspace are WSM licenses compatible?
