Hello @all,

i tested the upgrade from 7.4.7 to 8.0. Upgrading was done succesfull and OpenProject Server was reachable and accesible.

If i take a look at the output from the update process, i saw a hint for the requireing if utf8 at database (please see the attachment). We use MySQL 5.5.60 at Debain 8,  OpenProject database and tables are on charset latin1.

Should i first do the upgrade from 7.4.7 to 8.0 and afterwards the utf8 migration, or should i do the utf8 migration bevor i upgrade to 8.0 ?

Thanx for answer.

Many greetings and thanks for such a great piece of opensource software....

Hi Marco,

the UTF-8 warning was added so that new installations of OpenProject can get a warning before they use utf8 on MySQL versions 5.7 or greater, since MySQL's utf8 is not actually full UTF-8 support.

You do not have to address this warning if you're not planning to use 4-byte characters, and if you do, there is no difference in upgrading before or after.

For more information, please check out my other forum post here:

Also, an article on the technical details on why MySQL would make utf8 not UTF-8 at all.
