Maybe a silly question…

I want to migrate to percona, but no too fast.

Can I add a percona replica set to an existing (original) MongoDB cluster ?

And let it be for a while ?

Hello @David_Berlioz

Yes, you can use Percona mongodb server as replica, I would suggest doing full test before implementing this in production.

Percona Server for MongoDB is a free, enhanced, fully compatible, source available, drop-in replacement for MongoDB Community Edition with enterprise-grade features. It requires no changes to MongoDB applications or code.
