Migrating from DC to Cloud, can I synchronize Scriptrunner JQL before I move any issues?

[Pierre Ibrahim]

Hello,

I'm currently migrating from a DC installation to a cloud installation for JIRA, we're using scriptrunner and I had to do the initial JQL keyword sync described here: https://docs.adaptavist.com/sr4jc/latest/features/scriptrunner-enhanced-search/scriptrunner-enhanced-search-jql-keywords-synchronization

However as the page indicates, this takes a long time to finish. But it's only needed once, and then any "new" issues that are added shouldn't need another manual sync, but it should be done automatically.

My question here is can I just do the initial synchronization on an empty JIRA cloud instance? That way when I migrate all my issues, I don't need to do the initial sync that could potentially take weeks to finish?

If not, is there a threshold of tickets I need to have in my instance before I can do the initial sync? We're planning to migrate in phases (a handful of jira projects first, then another handful, then the rest, etc...). Would we need to wait till all the migrations are done before we do that initial synchronization?

Thank you all in advance.

Pierre
