It is similar to this one https://github.com/OpenMage/magento-lts/pull/1470. I prefer yours because you created a backup in a repository for all the deleted files to prevent issues with BC.

You have to agree with @luigifab which one will remain open.

ah! nice idea :-)

and we remove the "require" of this new repo from v20?

EDIT: actually why should this be in v19?

Go away :angry:

I prefer the current workflow with 19.x as the main branch, but it seems that i'm alone. It's WIP ... I'll join discussion about branching later :)

However, a migration script and clear and concise information are mandatory. Please check the other PR where this script was also included. A combination of ideas is welcome.

@fballiano i would neither add it to 19.x, nor 20.x.

I'd add it to your release-builder to maintain BC. Everyone who uses composer can add it if necessary.

i'm aware of #1470. I think we move into same direction ...

• https://github.com/OpenMage/magento-lts/pull/2526 is part of this PR (is requierd for my approach)
• https://github.com/OpenMage/magento-lts/pull/2527 just re-added this classes to an extension

So two things are left. Removal of deprecated xml nodes and migration script?
