We're migrating a test environment with two backend Policy Servers 12.52, to 12.7. The operating system is Red Hat 6.8 and documentation talks about adding the attribute BackwardCompatibleMode while migrating versions to avoid agent key update rollover problem. The question is that, when reading the "sm.registry" file of Policy Server, it has windows registry format and don't know how to add this value at unix file. We have searched knowledge and communities and found this tip https://communities.ca.com/community/ca-security/ca-single-sign-on/blog/2017/12/04/tech-tip-ca-single-sign-on-policy-serveran-agent-change-key-command-was-received-that-contained-a-set-of-null-keys but it's not solving the problem. Can you help us in how to add this value at sm.registry file over unix operating system?
The syntax should be : HKEY_LOCAL_MACHINE\SOFTWARE\Netegrity\SiteMinder\CurrentVersion\PolicyServer BackwardCompatibleMode= 0x1; REG_DWORD Note that this registry setting is available only from Policy Server 12.7
