Re: Version Woes

[Brian Bouterse]

I understand how maintaining the protocol compatibility wasn't an option.
It's actually pretty great the on-disk layout is backwards compatible. Your
guide looks pretty good. I have a few questions.

In my case it's the section at the bottom "Use Case: Remote to Local
(push)". My local is the 1.9.0b1 (Fedora) machine as my remote is the 1.2.8
(Debian) machine. What do you think the right process would be for me to
try? If it works for me I could send some docs back to your PR.

Is my first step to upgrade the remote Debian machine from 1.2.8 -> 2.0.0?
Can I use the "On Debian" portion of guide to upgrade that 2.0.0?

What version was the backwards compatible protocol version made? Is the
1.9.0 client the new or the old protocol?

Any other advice on the process I should try in my case?

Thanks for any info you can provide.

-Brian
