Vi have for +15 years had customers as tennants in our Jira Instance (Server -> Data Center) - all users licensed, with some "hacks" to hide buggy stuff and fields that does not support "tennancy".
Today we are a hybrid with about 10 customers on Jira (core/sw) and they are using many of the features as sub-tasks, linking, filter/dashboard etc.. Rest are moved to JSM. But these Jira (core/sw) users are relatively high issue volume users with a tight bond to our company.
Now we are moving towards cloud and are looking into getting the rest to JSM - but that would currently be pulling a lot of features away - with sub-tasks and linking to 2 most important..
So, any ideas how to mitigate this and add some of these and other features into their JSM experience, and make the transition a success. We are still in the very first process and are not fully familiar with the difference between Data Center JSM and Cloud JSM.
Good and factual recommendations regarding apps/solving of links and sub-tasks are more than welcome.
