Promotion to Band 8 in France

Hi, I am currently under the process of being promoted from B7 to B8 during the upcoming promotion cycle. I was wondering what percentage of salary increase in average should I prepare myself to expect. I know for experience that IBM usually don’t give high salary increase during ESP… Can you guys share your experiences after getting promoted what you’ve got and if you reached at least 0,8 PMR at your new band ?
