@mjopson has a decision been made on this? (for JIRA Server)

Also completely unable to use the Cloud service for legal reasons here. 

+1 on the Cloud vs. Server comment.  We are unable to use Cloud for legal reasons.

I hope you are correct, I've been observing what appears to be an ever-increasing gap of functionality between the platforms.

@chadalanjackson I assume that what Martin really meant, is that it's hitting Cloud right now and will probably get to Server releases soon. Usually, cloud gets things a bit faster.

Martin,

With all due respect... so what? We're not on JIRA Cloud nor do we plan on being on JIRA Cloud in the foreseeable future. This ISN'T an answer to the problem.  This doesn't help anyone on this thread.

The frustration that is coming across here is that this isn't the only time we, your paying customers, are getting these kinds of answers.

We can't go to cloud due to a myriad of reasons, mainly (in our case) because of the lack of support numerous add-ons for cloud.

This feature is now available in JIRA Software Cloud.
For more details please see Deleting a sprint

I strongly recommend to implement a feature to delete old sprints. 

Hi,

The possibility to alter historical sprint data in JIRA Cloud would be very interesting. Deleting closed sprints, changing start and end dates, etc. Strongly in favor of having this.
