Hi, I'm trying to upgrade my local caldav server installation from 4.2 to 6.0. When I run: sudo -u _calendar -g _calendar python bin/calendarserver_upgrade -f etc/caldavd.plist -s -D I get a weird exception: Traceback (most recent call last): File "bin/calendarserver_upgrade", line 12, in <module> load_entry_point('CalendarServer==6.0a.unknown-r14706S', 'console_scripts', 'calendarserver_upgrade')() File "/usr/local/caldavd/lib/python2.7/site-packages/CalendarServer-6.0a.unknown_r14706S-py2.7.egg/calendarserver/tools/upgrade.py", line 243, in main utilityMain(options["config"], makeService, reactor, customServiceMaker, patchConfig=_patchConfig, onShutdown=_onShutdown, verbose=options["debug"]) File "/usr/local/caldavd/lib/python2.7/site-packages/CalendarServer-6.0a.unknown_r14706S-py2.7.egg/calendarserver/tools/cmdline.py", line 110, in utilityMain service = maker.makeService(options) File "/usr/local/caldavd/lib/python2.7/site-packages/CalendarServer-6.0a.unknown_r14706S-py2.7.egg/calendarserver/tap/caldav.py", line 811, in makeService service = serviceMethod(options) File "/usr/local/caldavd/lib/python2.7/site-packages/CalendarServer-6.0a.unknown_r14706S-py2.7.egg/calendarserver/tap/caldav.py", line 1409, in makeService_Utility toolServiceCreator, None, uid=uid, gid=gid, directory=None File "/usr/local/caldavd/lib/python2.7/site-packages/CalendarServer-6.0a.unknown_r14706S-py2.7.egg/calendarserver/tap/caldav.py", line 1622, in storageService pgConnectorFromConfig(config), None File "/usr/local/caldavd/lib/python2.7/site-packages/CalendarServer-6.0a.unknown_r14706S-py2.7.egg/calendarserver/tap/caldav.py", line 1513, in subServiceFactory config, store=store, serversDB=serversDB File "/usr/local/caldavd/lib/python2.7/site-packages/CalendarServer-6.0a.unknown_r14706S-py2.7.egg/txdav/who/util.py", line 75, in directoryFromConfig serversDB=serversDB File "/usr/local/caldavd/lib/python2.7/site-packages/CalendarServer-6.0a.unknown_r14706S-py2.7.egg/txdav/who/util.py", line 185, in buildDirectory for recordTypeName in params.recordTypes: File "/usr/local/caldavd/lib/python2.7/site-packages/CalendarServer-6.0a.unknown_r14706S-py2.7.egg/twistedcaldav/config.py", line 75, in __getattr__ return dict.__getattribute__(self, attr) Should I first upgrade to 5.2 and from there go to 6.0? My only concern is PG database. Was there any schema change? Thanks, Nikola
