Do any of these support migrating the content of a Discord server (from some 3p archive tool)? Can anyone suggest a good archive tool? The open source project I help run has ~10 years of conversations, bug reports, feature requests, etc. sunk into Discord, and obviously I want to preserve all that (not sure we'll end up leaving the platform, but it's good to have backups anyhow). Our bug reports / FRs are in forum channels, and I've written a script to extract those and potentially import them into some bug-tracker. But I'd like something good that can archive the entire thing in a reasonable format.
