Hi @madhumohan! To get an idea of the steps involved in upgrading your Open edX instance from Ironwood to the latest release, have a look at the following resources:
- Upgrading from Ironwood to Juniper
- Upgrading from Juniper to Koa
- Upgrading from Koa to Lilac (which is the latest official release of the platform).
Since you’re using Bitnami, there might be some additional steps that you’ll need to complete; I’m not sure. But assuming that you can get a Bitnami installer for Juniper, Koa, and Lilac, it should be possible to follow the recommended approach of
… mak[ing] a fresh installation of the {Juniper, Koa, Lilac} release on a new machine, and mov[ing] your data and settings to it.
for each step of the upgrade process.
