Hi,
Hope you're doing well. My name is Nikhil Sharma and I'm a SugarCRM consultant. I've been working with SugarCRM since the last 8 years and know the framework really well. I started with SugarCRM when it was still in version 4. I have done multiple sugarCRM implementations including development, customization, upgrades as well as bug fixing.
Coming to the project, upgrading from 5.X to 6.X is a multi step process. We also have to be very careful about the custom changes that you've done to the system. If there are any non upgrade safe customizations, then I will have to make them upgrade-safe before proceeding with the upgrade. The upgrade-safe changes, if any required, will be charged extra. This is how I'm planning to execute the upgrade:
1) Study the system (CRM) and make sure that we are good to go with the upgrade. In this stage, I will mark all the areas which need special attention.
2) I will clone the system and create a dev environment.
3) I will perform the upgrade on the dev environment and do unit + system testing.
4) Once I establish that the system is performing normally, I will deploy the changes to production server.
5) Unit and System testing will be done once again on the production server before handing the system over to you.
I can confidently say that I'm the best candidate to handle this project because I know SugarCRM like the back of my hand. I can execute this task efficiently and quickly.
Let me know if we can take this forward.
ThankYou
