Hello,

I am currently managing a rental/leasing business using Odoo. Up until now, I was using the Rental module to track my products. However, I’ve decided to switch to the Subscription module for a more streamlined management of recurring billing (subscriptions) for my rentals.

My main challenge is that all my products are currently flagged as “Rental” as it is not possible to have both "Rental" and "Subscription" tags on the same product in Odoo.

Now I would like to unflagged "Rental" on these products and flag them as "Subscriptions". But Odoo does not allow that.

Could you please advise on the recommended approach to handle this migration? Here are some specific points I’m considering:

• Duplication Approach: Would it be best to duplicate my existing products and create a separate set tagged as “Subscription,” ensuring I preserve historical data from the Rental module? As I am using tracking by serial number, can I update my existing serial numbers to point to these new subscription products ?
• Direct Modification: Is there a safe way (e.g., via a server action or migration script) to change the flag from Rental to Subscription on existing products without affecting historical transactions and data integrity?

I would greatly appreciate any best practices, experiences, or recommendations from those who have faced a similar scenario.

Thank you for your help!
