Hello Nelson,

Same issue here. All the links provided here are for CE, but I'm trying to upgrade to EE same as you. I have a paid subscription but Im not reseller, so I don't have access to the EE git.

I downloaded the tar.gz from the download page, updated odoo.conf with the additional path, ran:

python3 /opt/odoo/odoo/odoo-bin -d MYDATABASE -i web_enterprise --stop-after-init

apparently ended with no errors, but even after restarting I see no enterprise version active...

Were you able to upgrade??? What you did??? THANKS!!!

Download the Source Tar file and copy it to a directory just like if you are doing the CE version.
EE comes with everything already. I had to learn the hard way.

#2 Download Source in Tar-ball compressed file, SFTP to home directory (PERFFERED WAY).
$ tar -xvzf odoo_18.0+e.latest.tar.gz << Enterprise version Full, no CE
$ sudo chown odoo18 odoo-18.0+e.20241024 << change ownership to odoo18 user
$ sudo chgrp odoo18 odoo-18.0+e.20241024 << change group to odoo18 user
$ cd odoo-18.0+e.20241024
$ sudo cp -r * /opt/odoo18
$ sudo chown -R odoo18 /opt/odoo18/* << change ownership to odoo18 recursive
$ sudo chgrp -R odoo18 /opt/odoo18/* << change group to odoo18 recursive
