will converting to Multisite mess my Membership setup?

Hi,

My site is a single site and it is running perfectly with Membership plugin. My customers can buy subscriptions, all works well.

I now wish to convert from single to multisite so I can install Marketpress and run an Etsy-style additional offering.

Membership currently sells subscriptions on my single site, and I would like it to remain doing so, as is.

If I convert that site to multisite, will it break my Membership set up?

And any words of caution regarding Membership and multisite, given the above scenario?

Thanks,

David
