Upgrading From 4.1.5 To 4.2.1 Without Loosing Customizations

Hi,



Please help me understanding the process of upgrading CS-Cart Multivendor 4.1.5 to latest 4.2.1 without loosing below content.


  1. Database changes
  2. Theme customization
  3. New code added
  4. Existing code changes

    etc.



    Reason: We are using Energo theme and they have launched the latest version of theme with lot many bug fixes but problem is there latest version is only compatible to latest version of CS-cart i.e. 4.2.1.



    We have already made lots of above changes which we don't want to loose while upgrade, so need to understand how can we come out of this situation without any loss.

    Most possibly only point #1 will be transferred correctly. Other items depends on the developers, but we almost sure that additional adaptation will be required. We strongly recommend you to make upgrade on the copy of your store to see the result.

Can I get estimated effort & cost of this task?
