The  below code works, good job.

```
-- Rename webdav to health_webdav3_server
update ir_module set name='health_webdav3_server' where name='webdav';

-- Rename webdav to health_webdav3_server
update ir_module set name='health_caldav' where name='calendar';

```


The last error when start service I faced is the below:
