PAM Upgrade

Hi everyone,
I have two questions regarding CyberArk PAM Self-Hosted upgrades and support:

• Is IDIRA planning to end support for older CyberArk PAM Self-Hosted versions, including version 15? Specifically, will customers be required to upgrade to version 15.2, or will version 15 continue to be supported?
• Regarding the upgrade path, is it supported to upgrade directly from CyberArk PAM Self-Hosted version 14.4 to version 15 or 15.2? Or is it mandatory to first upgrade to version 14.6 before proceeding to version 15/15.2?

I would appreciate any clarification or official guidance on these points.
Thank you!
