migrate data between columns

[Sam Matthews]

I have created a new custom column which will replace an existing column. The new column is a database lookup column, but I'm assuming this data gets loaded in the JIRA database somewhere.

How can I migrate the existing data (found in the existing column), which will eventually be removed and move this into the space identified by the new column?

Kind Regards

Sam.

What do you mean by "columns" here?  Do you really mean columns, or actually fields?

If it is a database lookup field (provided by one of the database field add-ons), then you'll need to extract your existing data and copy it over to the external database, then hack it into the internal JIRA database as well.
