+one. What is described here is the process to do it from
+Mastodon; on other software implementations, it will surely be somewhat different. All
+the steps regarding your
+.Nm
+account must be done from the command line. For the sake of the example, let's
+say that you want to migrate from an account named @origin@mastodon.example.com to
+another one named @destination@snac.example.org and that both of them
+already exist. I've used this very informative page as a guideline:
 .Pp
-To do this, download the user's list of accounts being followed (in CSV
-format) from the Mastodon web interface and execute this:
+.Lk https://fedi.tips/transferring-your-mastodon-account-to-another-server/
+.Pp
+
+1. On the web interface of your origin Mastodon account, click on
+.Vt Preferences
+>
+.Vt Import and Export
+>
+.Vt Export
+and download the CSV files under the "Follows", "Lists", "You Block" and "Bookmarks"
+labels. After being downloaded, you should find the following files on your download
+directory:
+.Pa bookmarks.csv ,
+.Pa blocked_accounts.csv ,
+.Pa lists.csv , and
+.Pa following_accounts.csv .
+.Pp
+2. From the directory where those files are stored, run
 .Bd -literal -offset indent
-awk -F, 'NR > 1 { print $1 }' /path/to/following_accounts.csv | \\
-xargs -n 1 snac follow $SNAC_BASEDIR $SNAC_USER
+snac import_csv $SNAC_BASEDIR destination
 .Ed
+.Pp
+This process may take some time because it depends on the availability / responsiveness
+of all the ActivityPub servers involved (webfinger, accounts, posts, etc.). Also, if
+.Nm
+complains that it can't find any of these files, please check that they really are
+in the current directory and that their names match exactly. Some of them may be empty
+(for example, if you didn't create any list) and that's fine.
+.Pp
+3. Again on your
+.Nm
+server, run
+.Bd -literal -offset indent
+snac alias $SNAC_BASEDIR destination "@origin@mastodon.example.com"
+.Ed
+.Pp
+Check that no errors were shown. If they do, the origin Mastodon server may be
+busy or down. Try again later.
+.Pp
+4. Move back to the web interface of the origin Mastodon account, go to
+.Vt Preferences
+>
+.Vt Account
+>
+.Vt Move To A Different Account ,
+and follow the instructions there. Set the handle of the new account to your
+.Nm
+one; as of our example, @destination@snac.example.org. This will start the migration
+process: it's the duty of your old Mastodon instance to send an automatic
+.Vt Move
+message to all your followers in their respective instances. According to the great
+document I linked above, this process may or may not start immediately, and its
+success may depend heavily on how all the servers involved behave. Just cross your
+fingers and hope for the best.

 .Ss Instance blocking
 Full instances can be blocked. This operation must be done from
 the command-line tool. See
