I have a plan that is at 4100, i have created a new plan but don't want it to start at v 1.
I don't think there is a way to share the build number between plans, and even if i could i think it's neater to just say the new plan starts at 10000. so there won't be any build number collisions
It is not currently possible to do it directly in Bamboo.
However, there is a way to do it, but it's not recommended. It requires direct database manipulation.
To do it, please first make sure your Bamboo instance is not running. Then, modify the column value `next_build_number' in the table `build' for the specific plan to your desired value, eg. 10001.
