Get all data past 90 day access

[dvnrsn]

I was able to get a lot of public channel data using mattermost migrate from slack and it's my understanding that if I want DM data especially beyond 90 days I will need to upgrade slack plan (currently free tier). I wanted to check if this understanding is correct.

I'm also missing some images and files prior to 90 days. Seems like slack is being stringent.

Hey @dvnrsn , I can only assume that it is so, never tried myself.
