It appears that we're running an unsupported version of Crowd and likely other versions of Atlassian. Our Jira/Crowd and a Confluence are running on Linux. We have our KB running on a Windows version of Confluence. Being new to these products, I need fairly detailed assistance with their upgrades, beginning with Crowd.
Here are the versions and SEN's that I was able to obtain:
| Name | Version | SEN | Atlassian Products | Primary Use |
| Confluence | 7.13.7 Build 8703 (Windows 2012R2) | SEN-8700883 | kb.domain.org/ | Process docs and board portal |
| Jira | Software 8.20.10 Build 820010 (Linux 5.4.0-109-generic) | SEN-9825639 | my.domain.org/jira | Task tracking and project mgmt for DS & support for Salesforce and admin calendar |
| Jira | Core 8.20.10 | SEN-9825639 | my.domain.org/jira | |
| MyConfluence | 7.13.0 Build 8703 | SEN-8700883 | my.domain.org/confluence | Resources and docs for DS clients |
| Crowd | 3.5.0 Build 1120 (Linux5.4.0-109-generic) | SEN-9825638 | my.domain.org/crowd | DS client user accounts for My and Jira |
