CKAN upgrade from 2.9 to 2.10

[s2074135]

Hi,

Does anyone have any recommendations on how to upgrade from CKAN 2.9.8 to CKAN 2.10.1? I tried to upgrade by simply adjusting the following line in my Dockerfile

from FROM openknowledge/ckan-base:2.9.8

to FROM openknowledge/ckan-base:2.10.1

but that generates a lot of errors such as

subprocess.CalledProcessError: Command '['ckan', '-c', '/srv/app/ckan.ini', 'db', 'init']' returned non-zero exit status 1

or

ERROR: column user.last_active does not exist at character 278

Seems not to be the right way.

Thanks for any hints!

Thomas
