What should work, but haven't a test-case for it, is to use the 
contributed
set-policy from the enforcer.  Create a new policy in your kasp.xml with
all the same parameters, except from the new algorithm.  Then (re)import
the policy.  Then one be one move zones to the new policy.  You will 
have
to enforce the zones manually to ensure they start the rolling policy
probably.

Relevant commands:
   vi kasp.xml
   ods-enforcer policy import
   ods-enforcer zone set-policy -z example.com -p newpolicy
   ods-enforcer enforce -z example.com

One caveat to think of, I probably wouldn't use this on combined signing
keys (CSKs).

If possible test this first, we've used set-policy but not for this
specific case AFAIK.
