Migrate from django-celery and keep older results

Hi @mauroka . I think you need to migrate your data manually between those 2 tables. If you need we can try to make PostgreSQL (or MySQL?) script to migrate data from old table to new django-celery-results table.

Thanks a lot.

Hi @wardal

We have made an SQL migration from djcelery to django-celery-results but we are facing one problem with the meta field.

In djcelery the value is decoding with pickle to something like this:
eJxrYKotZIzgYGBgSM7IzEkpSs0rZIotZA5VsTRKSTSytEjUNTNJNdM1MTMw001MSknVTU02MTAzSzQxTjQxKGTxa/NrK2RNLNYDAMOfE9s=

While django_celery_results_taskresult expected something like:
{""children"": [[[""92da298a-64e6-4606-abde-ec4066a43a40"", null], null]]}

If I decode this value in order to save it in the django_celery_results_taskresult table I get a different structure from djcelery:
{u'children': [(('92da298a-64e6-4606-abde-ec4066a43a40', None), None)]}

Any ideas to solve this besides parsing the data?

Thanks a lot.
