I made the migration of one of the servers I manage. Everything went well enough, as is usual in this type of operation, if we use the Debian distribution, but attention is needed, as there have been different conflicts that must be analyzed and resolved one by one.
For some packages, the new versions contained in Trixie constitute an important step forward. In particular, the syntax of Dovecot configuration files has changed considerably. Attention is recommended in the migration of servers currently in production.
