Company split impact on h1b nad GC

[MVS 0]

My company is splitting into two serve public and private sectors separately. what would be this impact on my h1b and GC process. Company names may change, but i will be working on same location with the same client. My i-140 has been aprroved with the PD in 2012. My question is "Do I need to restart my GC process", once split is completed.
