How difficult is exporting from one provider into another (e.g. from gmail into proton or purely)? I guess normies like me are a bit hesitant due to the risk of messing it up (would be a disaster to lose years of emails, as some are important for record-keeping). Curious to hear from people who've done(/attempted) it and how it went? Was it hard? Were there risks? Any regrets?
