This is my first stab at upgrading directly from Django 1.6.11 to 1.81c
to see what needs to be done. I thought I'd skip 1.7.x - is that a bad
idea? Is there some step in 1.7.x which eases the path to 1.8.x?
On first starting the project up using runserver on localhost it advises:
Python: 3.4
Django: 1.8c1
Database: ssds.climate.com.au
Postgres: 9.1
16:18:54
Performing system checks...
System check identified no issues (0 silenced).
You have unapplied migrations; your app may not work properly until they
are applied.
Run 'python manage.py migrate' to apply them.
See below. Not sure where to go from here. Any ideas?
Thanks
Mike
