KPMG INDIA BACKGROUND VERIFICATION : Offer letter there but no experience certificate (Please advice)

Hey Guys,

I will be shifting job where the new employer has a background verification by KPMG India . I have more than 10 year experience and have received proper work experience certificate from 4 earlier employers. But, my current employer has poor HR policies and very rarely issues experience certificate & salary slips.

I do have offer letter, form 16, resignation mail etc.. So will these other documents be sufficient for KPMG background check.

Please advise what plan of action should i do
