Hi,
like most companies we are forced to abandon our server products and need to move to the cloud.
We use Jira Software, Jira Service Desk (and Confluence).
Our plan was to move everything 100% as is to the cloud, which means users, groups, projects, workflows, fields, etc.
As I learned today, there is no Service Desk in Cloud any more and we must use ITSM instead. But unfortunately our migration tool says, that it can't migrate from SD to ITSM. 
What is the best way to move from Jira Service Desk to ITSM? Are there any recommendations?
I assume we have to "upgrade" our server from SD to ITSM first, and then push all the data into the Atlassian Cloud. Or is there another way, like exporting/importing existing issues straight into ITSM?
Thanks in advance
Robert
