Cloning a ledger

[Piyush_Bedi]

Is there any method to take a dump/snapshot of a ledger and load it into sandbox/other ledger?
This would be quite useful for creating a temporary test environment or a support environment that mirrors production.

There is currently no way to do that out of the box.

You could consider using the SQL persistence feature on Sandbox. I’m not sure if it would cover your use-case, but it sounds like it …

Persistent Sandbox State?

Is there a way to persist the sandbox’s state so that it doesn’t get lost if I stop and restart the sandbox?

DAML Sandbox Persist with oracle database

Hi, Quick question - i know in your documentation you mention you can persist a sandbox instance to a postgres database which works great. I was wondering though as it uses a standard jdbc connection url would it be possible to switch out a postgres database with an oracle one? I have attempted it myself with no luck but wasnt sure if that was to do with my local configuration so thought Id check here if anyone else has tried? Many thanks in advance Cheers

That works from Sandbox to Sandbox (within one SDK version), or from daml-on-sql to daml-on-sql (for obvious reasons), but it doesn’t help you move a daml-on-fabric ledger to Sandbox.
