Hi.
Updating process for your dolibarr version isn't problem and I can do it without problem.
The only problem is that we dont have any way to push a new app into Softacoulus platform unless that you're shared hosting owner.
Open to questions,
I am working on Dolibarr. Please explain your project/work in details in saikatcdac at gmail dot com. I have an experience on basic module creation and Dolibarr modification.
