We need to generate a release in 3 weeks, and for the planning we are doing today we don't have coherent logical user stories from the backlog tasks. Is valid to match say each development task is equivalent to an user story?

Methodologically what is the correct way of handling this?, because anyway we are going to have standup meetings and we are going to control the progress of the project against those development tasks.

For example, we have things like:

. Adapt ETL to process numeric lists

. Adjust licensing component

. Remove DTC

and so on.

So, for the planning poker and iteration planning is valid to use those tasks? if not, what is the alternative?
