Data science for a Data Warehousing Engineer ( Test Analyst)



Hi -
I have been working as a DWH Test engineer. I want to switch my career from DWH testing to Business Data analytic. So i am going to opt for a course in R programming .How well this is a good choice ?
Also i am little concern about my experience , Since i am a DWH tester , Will the companies consider my 5 year Experience in testing while i switch my career into Business Data Analytic ?

It would a great help if there is a guidance here. I am confused…
