If one task is blocked by another (i.e. dependency exists), most project management tools cause the dependent tasks to push if the blocking task changes.
For example, initially Task 2 (Start 5/5, End: 5/7) is blocked by Task 1 (Start 5/2, End 5/4)
If I then push the end date of Task 1 to 5/8, I would expect the Start date of Task 2 to automatically move to 5/9. Is there a way to do that in Jira?
Data Center: Automation will be able to do this, but it isn't native yet, it's coming before 30th June 2022 - see this article for more information
Server: There's no native option for this platform type, given it is EOL
For DC/Server, you could use the Automation app from the Marketplace - for DC use it as a free trial until it becomes native - or use a different automation app, such as Scriptrunner
Assuming you have access to standard Automation - this is how you could do it:
Trigger: Field Value Changed
Field: Start Date
Branch: Linked Issues = blocks
Action: Edit Issue
Start Date - copy from Trigger Issue
Copy from... operation is available via the 3-dots icon
You can customise the rule as needed around other fields, etc.
Note: If the Issues can be in multiple Jira Projects:
You'll need to use a Global Automation rule, created via Jira Settings > System > Global Automation
Global Automation rules have execution limits if you are on Cloud, depending on your plan type:
Free = 100 per month
Standard = 500 per month
Premium = 1000 per paid user, per month (eg. 200 users = 200K)
Enterprise = Unlimited
Let us know if this helps, or if you need any specific help with setting up the rule!
