I tried a reckless approach.
First, I migrated the database (mongodb).
Then, I directly copy all the files on the original server to the new server
Finally, modify the uri variable in config.json.
So far it looks successful. . .
@AOKP Because i dont (yet) have money to afford a big vps
So.... what does that mean for your customers? It only takes a $5 VPS to have many NodeBB instances. Is it that your customers total revenue is under $5? I'm confused. You would have to be spending way too much money to have one VPS per instance, yet you say your are too poor. Those two things don't go together.
I ont host more than one noddbb in 2gb ram, 2,4ghz and 1 core that costs me $5
