Scriptrunner - Change IssueType for IssueType in Scheme for many Projects at onces

[Nicolás Figueroa]

Hello,

Im in a migration process and before migration We are using a DTC preprod to merge configuration on projects in a Bulk.

One of the steps is to change wfs and issuetypes for new a model.

Example in the old IssueType Scheme exist 10 different IssueType

The new model only have 6 IssueTypes and all will have a correspondance with the old ones.

This process with the native tool of change IssueTypes is a very very large process and many times its fail cause Error 500 or TimeOut.

For these reason Im trying to find another solution, Where maybe in a script I can have the correspondance of old to new IssueTypes in the Scheme.

Actually We are doing this process in bulk of 50 projects(more than 1000 total) and with many Issues, so the process takes hours.

Specs:

Jira Software 7.3.6

Migration from Server to DTC.

Any sugestion or solution could be great,

Thanks in advance.
