EB2 to EB1 Upgrade

I worked for company A for 7 years in India. During that time they had filed my L1B . Later I left that company and joined company B in USA. Company B filed my GC in EB2 category. I have been with company B for almost 8 years now.
Meanwhile company A’s USA office wants to rehire me. Is there any chance of me upgrading my EB2 into EB1 if I join company A using my almost 10 years old L1B as I am moving to the same old company, but this time USA office
