1. The metadata for your SP should be the same, irrelevant of which
IdP you want to use. That also means you direct user agents to
specific SPs by other means.

2. You should not use /Shibboleth.sso/Metadata except to generate an
example from which to work. The same (and more) can be done with the
included metagen.sh script. See the first and third paragraph at:
https://wiki.shibboleth.net/confluence/display/SHIB2/NativeSPHandler#NativeSPHandler-MetadataGenerationHandler

3. The Location attributes of the init:RequestInitiator and
idpdisc:DiscoveryResponse elements should point to the SP, not the
IdP. If your SP points to "old_idp" then your SP config is wrong.

There is no file for that. You'd need to look at the source where it
comes from but the assumption is that you don't need to know (or
change) that.
