This part is very generic to almost every migration out there. Should we instead just point to some resource in the module level doc (mod migrations) and keep mod v1 docs concise?

Where are you suggesting we move the generic migration docs to ?

Potentially here (if you feel it needs more explanation)? There is also a storage migration tutorial which hopefully is easy to find.

Thanks a lot for improving our EPM docs. ❤️
Made some comments/nits but see no reason to block approval.

I have seen that in all your doc PRs you are not really doing the linking correctly, please be more careful with that.

Please keep the principle of remaining concise and DRY in mind.
This whole block should be:

All of these statements are more or less about what migrations are and in a generic sense.
If I take out Election Provider Multi-phase our of this block and replace it with Any Other Pallet all of this still holds.
This means you are documenting the wrong thing here. You are documenting what a runtime upgrade in general is, NOT what the runtime of this pallet is doing. This generic information about runtime upgrades in general, if they should be anywhere, should be on the OnRuntimeUpgrade or Hooks traits. Or, in an external website or elsewhere. Then, you link to that external resource here, rather than potentially copy-pasting this everywhere.

I am happy that you and @aaronbassett are giving this a shot, but
- I don't see https://github.com/paritytech/substrate/blob/master/docs/DOCUMENTATION_GUIDELINES.md and more importantly the 5 principles mentioned https://forum.parity.io/t/new-polkadot-substrate-documentation-plan/1810 being respected here.
- I do want to warn you that no documentation is strictly better than wrong documentation. As you are getting closer and closer to domain specific extensive pallets (such as this one), please consult the correct owner (= whoever knows best about the pallet) and try and work with them to write this, rather than taking it all on yourself. Example, I think you having requested review from @Ank4n and @gpestana is the def. the right thing to do 👍
