Would you explain more the point : port the module to the required version yourself? do you mean upgrade? in this case upgrade the geoengine tool from v10 to v11? if i get it well.

If you want to use a particular module, then you have the following options:

- Use the same Odoo version as the module is available for

- do port the module to the required version yourself

- pay somebody to port the module to the required version.
