Merging nodebb forums

[oPignonLibre]

Hi,

I would like to know if there is a recommended way to merge two nodebb forums ?

I converted some threads using the mybb import plugin but the original db was so big I ran into issues (plugin crashing) and couldn't convert the whole forum. I limited my import to the most popular threads, keeping only posts less than 1y old and it worked. But it was so time consuming that I decided to upgrade nodebb instance and made it available to users. Since the import plugin requires nodebb v1.0.0 my idea would be to create a new nodebb instance with its own mongodb and import the remaining threads/posts, then upgrade it to the same level as our "production" one and try to merge the imported threads to the "live" nodebb.

Has any nodebb merge been done before ? Suggestions ?

Thanks
Thomas
