I understand how the B2B software envrionment works where the users are different from the decision makers. As the decision has been taken to move from Clickup to Jira, I would suggest that you prepare an inventory of current and archived projects that you may need for daily work and reporting purposes respectively.
Next would be to identify tasks, lists and projects from Clickup and import/ create from scratch into Jira. Mapping to the issues, projects and other objects would need a bit of effort in the first attempt.
If the projects are very simple ones, then you can also export the project details as CSV from Clickup and try to import into Jira. While this would not be a one click solution, but it would save your time that you would otherwise have spent manually copying and pasting text and dates etc.
Also, as the previous poster replied, Jira could fall short in the long run.
Hope my current approach helps you to get started.
