Hello Rodrigo,

To migrate subscriptions from OSE Membership to Payplans, you need to write migration script. Currently Payplans don't have any migration tool, so need to write migration script according to data (from ose membership).

By the way, Payplans 3.6.3 no longer support with Joomla 2.5 version.

We do provide migration service also. If you want migration of data from OSE to Payplans then send us detailed quotation request at support@stackideas.com OR https://crm.stackideas.com and select "Customizations" .

Let me know if you have any query.
