What is the best / fastest way to update a field for all issues matching a condition?
After a bulk data import, we have some temporary fields
i.e. 'Assignee (T)'
I want to update 'Assignee' to myself, where the 'Assignee (T)' field contains my name.
This can be done as a bulk operation, but limited to 1000 Max and there are over 35K. Not all mine, but will need to re-run for various users and with 5 other (T) fields.
I was thinking scriptrunner, is this possible?
Does anyone have a good starting point?
