BQ27510-G3 calibration and Golden Image Generation

Hi all

We are using BQ27510-G2 in our existing product. I already taken Calibration for 20 Boards using BQ27510-G2 and generated Golden File.

Now we are changing to BQ27510-G3 for that we are going generate new Golden Image for BQ27510-G3.

For that I like to know the following

For generating new Golden File can I use the average Calibration data colleacted using BQ27510-G2 or we need to take new Calibration for 20 Boards Using  BQ27510-G3.

I need to now the difference between BQ27510-G2 and BQ27510-G3.

Where can I get the TRM for BQ27510-G3.

Error in opening "http://www.ti.com/general/docs/lit/getliterature.tsp?baseLiteratureNumber=sluua97&fileType=pdf" got from BQ27510-G3 Data Sheet.

Thanks
