Deactivating S2Member on multisite – advice?

Hi,
I recently set up a site on my multisite wordpress installation using s2member pro. When I installed it I activated it multi-site-wide. I then developed the site and it is now successfully up and running.
I subsequently realised that s2member is active on all my other sites, and also may be conflicting with one of the themes I use.
I would like to de-activate the plugin sitewide, and then reactivate it solely for the site that uses it, but I am worried that I will lose the configuration and have to try to remember exactly how I set it up (and consequently have down-time).
Can you advise me what the best method would be to do this, and should it be hassle-free?

Many Thanks

If you are running s2Member Pro, there is an Import/Export area where you can export your s2Member configuration and then import it back into the new site if you need to. That being said, if you reactivate s2Member on the same site as it was previously active, you shouldn’t lose anything :-)

See: s2Member -› Import/Export (in your WP Dashboard).

I suggest creating a backup of your database before doing any of this. Just in case.
