Can I use DW 3 and DW MX?

Will DW MX overwrite DW 3?

[queequeg]

I have DW 3 installed on my EMac, which runs both OS X and OS 9.2. If I install DW MX (an OS X only application)will it automatically "take over" all of my Dreamweaver 3 site setup and site files, or will I be able to continue to work in DW 3 as before (in OS 9.2), while I learn how MX works(in OS X)?
Thanks!

Not sure if it's the same for an upgrade from DW4 to MX but when I made the swap it was fairly simple. DW4 still works, although I dont use it now at all now.

All your site definitions should be copied so you can sill use the older version if you like.
