Yikes! I hate to say it, @BILL SCHWARTZ, but there is no easy way to do this with that older version of Jira server. The Atlassian migration tools only support 7.6 and newer.
How "big" is your server site (how many issues & projects do you need to migrate)?
We have the simplest possible configuration - no apps no links no extra anything. There are only 5 users and we use only the most basic functions. We have 10-15 boards and some active sprints and backlogs. Total DB size is 30G. 474 issues, 670 attachments, 2565 comments, 25 components, 13 custom fields, 14 projects, 28 screen schemes, 53 versions... does that help?
IMO, this means that you'll likely get most of what you need (vs. if you had a much larger server instance).
AFAIK your only option is going to be exporting your server data into a CSV and then importing it to cloud. See 'Import data from a CSV file' for more information.
Upgrading to a supported version of Jira first would be our recommended approach. To be honest though, nothing is stopping you from manually installing and running the Jira Cloud Migration Assistant on an unsupported version - we just can't guarantee that everything will work as expected.
I work closely with our support teams and have seen many customers with similar data shapes migrate successfully on older versions. Give it a go and if you get stuck you can always reach out to our migration support teams here!
