Missing REST end point and Behaviours feature on Script runner for JIRA cloud

[shrikant maheshwari]

HI All, 

I have many Rest End points and Behaviours Scripts in JIRA server and now when migrating to JIRA cloud , the script runner for JIRA cloud does not support the below features - 

1) REST end points

2) Behaviours

Could you let me know what can be the alternative for that ?
