Hey,

I am willing to change the technical name of a module on an existing database. The operation happens in 2 steps : create a duplicate of my module with the new_named. Uninstall the old_named module.

Now, uninstalling the old_named module removes all associated fields. The new module recreates them, but of course, the tables are empty.

How could I proceed to change the technical name (module's folder name) without loosing data in the database ? (there is no change involved in the code itself) tks

You can remove the old module from the file system, without uninstalling it.

Restart openerp-server

Then, you can add and install the renamed module: existing data will not be lost.

Thanks for the tip, this solution works. Though, it doesn't allow me to fully remove a module. Nevertheless, the fields are now declred in a new module, and data was kept intact.

I didn't try, but maybe you can simply remove the old module from the ir_module_module table

indeed, but there are many dependents on ir_module_module (ir_model_constraint, relation, dependency, etc) ... that I wouldn't interact with by hand.

Or manually set it as uninstalled?
