Our department recently went to a network version of AutoCAD 2006 with the IT managers instructions (in his email) to remove all older versions of AutoCAD. I went against his instructions (don't tell) and kept the stand alone copy of 2005 installed. I mainly did it for the migration process (which, by the way is the best I've seen out of any other release).
Is there any problems that might come from keeping the older software on the machine. I think it helped me because it kept all my settings and the time it took me to adjust to the newer version was zero.
Any thoughts?
Thanks
