overwriting data during concurrent update

[Mike Anthony]

If a plug-in is used to synchronization two JIRA instances in a separate environments - The question is: If a developer opens Ticket #999 in the development environment and a Project Manager modifies the same Ticket #999 in production, does the modification made by the PM in production overwrites the inputs originally entered by the developer in the development environment or will the ticket #999 reflect inputs entered by both the developer in the development environment and also inputs of the PM in the production environment?

Imagine the synchronisation user is a human typing things in.  You'll get the same timing cycle as a human reading one issue and having to copy and paste its data into another system - both changes will be recorded in the order they are posted in each system.

Hi Nic,

Thanks very much for your response very much appreciated.

 Quick question can you say the same to this?

We are looking at using Backbone plugin to sync to JIRA databases in Development. The question is, will the backbone plugin merge and also ensure data consistency in the two databases or are we looking at data variations from the two databases?
