I've been searching the forum and it seems some keep older versions some don't. Should I uninstall 4.0 before installing 7.0 . What are the plus and minuses...will all my 4.0 projects come up in 7.0.? Do plugins etc. change.
I don't know any disadvantages.
Both should be able to co-exist without any problems
Some older plug ins will work better with Version 4.0
But there are a lot of newer ones, especially VST plug ins, that work with 7.0
One thing I forgot to mention
If you drag a 4.0 veg into 7.0 and save it, it will never open in 4.0 again.
7.0 vegs can't be opened in 4.0
If it's important to you to keep them separate, you may want to create separate files for both, because all the 4.0 vegs will soon take the appearance of 7.0 vegs
