+### Starting from Peatio from 2.3.48 wallets settings stores in Vault. Since all settings should be moved to Vault, we need to recreate wallets in Peatio.
+To do this, follow these steps:
+
+1. Execute into Rails Console and run:
+
+```ruby
+  result = Wallet.all.map { |m| m.attributes.except('created_at', 'updated_at') }.map { |r| r.transform_values! { |v| v.is_a?(BigDecimal) ? v.to_f : v } }
+  result.each do |w|
+    w.except!('settings_encrypted', 'id')
+    w['settings'] = Wallet.find_by(address: w['address']).settings
+    w['kind'] = w['kind'].to_s
+  end
+
+  File.open("config/seed/wallets_backup.yml","w") do |file|
+     file.write result.to_yaml
+  end
+
+  Wallet.delete_all
+```
+
+1. Put content of the `config/seed/wallets_backup.yml` in the `config/seed/wallets.yml`.
+2. Change the Peatio version.
+3. Run `rake db:migrate db:seed`. It will migrate DB and seed wallets into Peatio.
+
+### If you are using Peatio 2.3.62 or higher and you need to move to another Vault instance you will need to export wallets settings and user payment_addresses and import it to the new environment.
+To do this you will need to process this steps:
+
+1. Export wallet settings:
+
+```ruby
+  bundle exec rake export:wallets
+```
+
+2. Export user addresses:
+
+```ruby
+  bundle exec rake export:addresses
+```
+
+3. Put content of the `config/seed/wallets_backup.yml` in the `config/seed/wallets.yml`.
+4. Change the Peatio version.
+5. Run `rake db:migrate db:seed`. It will migrate DB and seed wallets into Peatio.
+6. Import user addresses:
+
+```ruby
+  bundle exec rake import:addresses['file_name.csv']
+```
