Actually, not that difficult. All this does is it uses the Reddit API to download the content and creates an SQL script that restores the data directly into the SQL database of a Lemmy instance. This means, it doesn’t actually touch the Lemmy instance at all. You just run the SQL script directly on the database and Lemmy can then access the data from the database as if it had been posted on Lemmy over the last few years.
The only hard limit here is the size of the database. As long as you got enough disk space for the database to handle all that content everything is fine.

Could the lemmy instance survive that load? There’s way too many good posts I am afraid.
I think it can, it is not only Lemmy, but the whole Fedeverse backing them. But not sure… we have the other backup though
Isn’t it only the instance that owns the community that gets the files?
Regardless, text posts are basically “free” to host, so afaik uploading these wouldn’t have negative consequences

There is a Github repo with a tool for migrating posts from Reddit to Lemmy
