Hello,
I'm moving Jira 8.15 + Jsm to cloud and would like to share experiences.
Regards,
Guillaume Mackowiak
Since there are over 50 entities that need to be reviewed prior to migrating to the cloud, you should enlist an Atlassian Platinum partner. I work at Praecipio and we perform many migrations for customers both huge and small. All of our Atlassian engineers and architects are Atlassian certified with a couple holding all of the Atlassian certifications. Website is https://www.praecipio.com
