Hi Sanjay,
Based on R12.52Sp1 bookshelf, -xa option has been deprecated and has been superseded by -xe and -xp option.

A bit detail on some of the option that you mentioned :
-xe = Exports the object types that are related to the execution environment.
e.g ACO, HCO, Authscheme, User Directory, Agent, AgentGroup, TrustedHost,VariableType,SharedSecretPolicy etc
-xp = Exports the object types that are related to the policies.
e.g Domains, Policy, realms, rules etc
-xs = Exports the entire security data.
e.g Admin
-xi = Exports the object types that were initially installed.
e.g AgentType, AgentTypeAttr
So I believe, for your use case it is sufficient to use -xe -xp -xs options.
You don't really need to use -xi option as this will export object type that were initially installed which you most probably will already be having in your new policy store if you have imported default policy (smpolicy.xml).
Please give it a go and let us know if you face any issues.
