Errore durante l'aggiornamento da Rails 3.2.22 a Rails 4.2.4

Question

Sto provando ad aggiornare la nostra app da Rails 3.2.22 a Rails 4.2.4 con Ruby 2.2.3.

Ecco che cosa ho fatto finora:

1. Modificato Gemfile per specificare rails, "~> 4.2.4"
2. bundle
3. bundle update rails

La trascrizione integrale è al di sotto.

ActiveRecord non è specificato nel nostro file Gem, quindi non capisco cosa ha bloccato o dove ripararlo?

vestal_versions gemma ha dipendenza ActiveRecord 3.0.

È necessario unspecify versione di vestal_versions gemma nel vostro Gemfile, o specificare di 2.0.0 e poi:

bundle update rails vestal_versions
