Upgrade indico-plugins

Requirement not upgraded as not directly required: vine>=1.1.3 in ./.venv/lib/python2.7/site-packages (from amqp<3.0,>=2.1.4->kombu<5.0,>=4.0.2->celery==4.1.0->indico>=2.1->indico-plugins) (1.1.4)
indico-migrate 1.0 has requirement indico<2.1.dev0,>=2.0, but you'll have indico 2.1 which is incompatible. 

when upgrading from 2.0.1 to 2.1 …so for 1.2 users they have to upgrade first to 2.0.1 ?


Migrating from 1.2 to anything >=2.1 is not possible and will never be - so yes, they will have to install 2.0.x first. I actually added a notice about this to the migration docs yesterday.

You can safely ignore the warning about the incompatibility, or even just pip uninstall -y indico-migrate to get rid of the migration tool since you probably don’t need it again.
