Can I retain all my data if I decide to purchase plugins from plugin developer?

Hi guys,

Sorry if it’s a really stupid question – I don’t really know too much about this stuff.

If in the future I decide to purchase a plugin from the actual plugin developer, but I had already been using one downloaded from here, how do I go about that?

Does it require any manual database management? Or do I delete one plugin and install the other, and it just works?

Hope this makes sense.

Thanks in advance!
