@gotwf 9.5 (Ya I know is a very old version )

Thanks for the reply, reason for changing to MongoDB is because I am using a very old PostgreSQL version in Ubuntu 16.04 and having some problems integrating with NodeBB, but in the end I decide to upgrade to Ubuntu 18.04 and upgrade the pgcluster to PostgreSQL version 14 and it solves my problem

Hi now I am hosting a nodebb forum with the PostgreSQL database and now I wish to switch to MongoDB, can anyone provide me with a guide for migrating "nodebb" database to MongoDB?

May I know is the any plugin that support to to search for the content of the attachment like pdf, word?
