Hey,
when I switch from Ajax Search Lite to the Pro version, should I use the Maintencance – Wipe & Deactivate functionality in Lite before I uninstall it? Will this affect anything in my Pro settings?
You can use that option, it will not affect anything within the Pro version, the plugins are completely separate.
It is not neccesary, but you can do it, if you don’t want to switch back to the lite version – it clears unneccessary database entries files etc..
