Changing emails is potentially dangerous, but I have started doing it anyway. I have taken the “slow migration” track. Every time I log in to a site that uses my old email, I update it to the new one (it is too time consuming/tedious to update every login in one go). I also automatically forward my old email address to the new one so I don't miss anything. I respond with the new one in hopes that others will start using it in the future. If changing emails is a pressing matter, you could set up a vacation response in your old email and tell people where they should reach you in the future. Then, you need to change all login information for everything. It's a good idea to retain access to your old email for as long as possible in case you forget to change a login, need to reset a password, recover an old account, etc. It is also nice to make sure people who don't have your new email can still reach you. Because switching emails was not urgent for me, I've chosen to slowly migrate. This process would be a lot harder if I had not been using a password manager.
