Can anyone help me upgrade from 7.6.2 to latest version?

Hi,

I need to move my gitlab installation 7.6.2 to a new server. As far as I know the oldest version possible to install in 7.10, therefore I need to upgrade to at least 7.10 to be able to make the move. I tried to upgrade to 7.14.3, but ran into trouble described here: 502 error after upgrade from 7.6.2 to 7.14.3

Can anyone help me? I will pay for your help

Thanks,

/Per
