You just upgraded to Ektron 9.00 or 9.10, and now you are unsure if you need new license keys.
If you upgraded from an Ektron 7.60 or earlier, then yes, you need new licenses. Contact the license team email@example.com.
If you upgraded from any Ektron version 8 product, you do not need new licenses. Ektron 9.00 and 9.10 continue to use the licenses from any version 8 product. As long as your license key ends with an -8, it will work in versions 9.00 and 9.10.
