Copy/paste from older versions to new works most of the time.
Things to note:
1. You must open VideoStudio at least once before you attempt to copy/paste - especially if you copy and paste items in the VFX_plug folder.
The VFT_plug folder doesn't seem to have that problem
2. Some items from older versions do not work if your operating system has changed. For example the
timecode plug in works with XP but if you alter your system to Vista, if you copy that plug in across it causes VideoStudio to crash the next time you open it - though it fixes itself and will open next time but that plug in will not have been recognised.
3. Some plug ins require other files to be installed on your hard drive.
For example the Burger
FX Bench Video Filters require certain other files to be present. You can still copy/paste the VFT file over but once you open FX Bench you will then need to tell it where those other files are located.
