[ECODP-dev] Migration 1.7 1.8

I'm not sure what you are referring to here, can you elaborate? If you have
the latest versions of the code before you build your RPM then a further
Git pull should not be required.

What do you think ?

I'm not sure which create table command you are referring to here. In
general however this sounds very dangerous to me. If you are running
something to create tables that already exist this sounds like an error and
should fail. We don't want to lose data here by dropping tables that should
not need to be recreated in the first place.

Are you running through the commands starting with a clean CKAN 1.7
database? If not, I would expect some of the commands to fail.

I will have a look at these two issues, it is possible that there is a bug
or misconfiguration in the storage system as it has not been used in the
project to date.

Regards,
John
