Add this to your procedure:

Important
Note that the database binary data file formats are not backwards compatible, so once you have upgraded to MariaDB 10.1 you will not be able to switch back to any previous version of MariaDB or MySQL unless you have a proper database dump. Therefore, before upgrading, please make backups of all important databases with an appropriate tool such as mysqldump.

What do you do with the obsolete packages? Autoremove won’t delete them, so should they be deleted manually?

I am a new user of Debian/Linux and am trying to upgrade from Jessie to Stretch. I followed your instructions as best I could but nothing happened. I reviewed every system response I got as I executed your instructions and noticed a different response when I executed “apt list --upgradable”. The response I got was “Listing… Done” and nothing to be upgraded was shown. I assume I have done something wrong prior to this step.

I executed the “su -” command so I am the root.

Thanks,
Abe

Everything seemed to go well unitil trying to reboot. Get bash and Jessie. Old-school–wipe and reinstall w/iso. Always works… Bummer! I really liked it much better when synaptic would offer the distro upgrade. OK, I’ll attempt this again w/o terminal and gui…
