I am looking to upgrade UCCX 11.6.2.10000-38 (ES02-28) to 11.6(2) ES06 in order to fix Cisco Unified Contact Center Express Privilege Escalation Vulnerability - see __https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-uccx-privesc-Zd7bvwyf
The ReadMe-UCCX-11.6.2.ES06.docx attached says these are the only valid upgrade paths
Cisco Unified CCX 11.6(2) ES06 is delivered as a Cisco Option Package (COP) file. This COP file shall be installed ONLY on systems that have following versions:
• 11.6(2) FCS Build - 11.6.2.10000-38
• 11.6(2) ES01 - 11.6.2.10000-38 (ES01-9)
• 11.6(2) ES02 - 11.6.2.10000-38 (ES02-23)
• 11.6(2) ES03 - 11.6.2.10000-38 (ES03-39)
• 11.6(2) ES04 - 11.6.2.10000-38 (ES04-24)
• 11.6(2) ES05 - 11.6.2.10000-38 (ES05-9)
We have System version: 11.6.2.10000-38 (ES02-28)
Will this work?
