upgrade mavericks server from lion server make problems

Hi.

I am in trouble after upgrade my mac mini 2011 from lion server.

Fitst, one of my calendar is removed while another one is remain.

: I don't know how to restore removed calender using timemachine file (/Users/(user)/Library/Calendrs)

or how using dumpall.psql.gz file in Backup folder (/Library/Server/Migrated/Library/Server/PostgreSQL/Backup)

Second, L2TP VPN is not working anymore.

: I have no file systctl.conf in /etc folder

Third, wiki is working well with my ipad2 (ios7.0.3) only.

Crome and Safari on PC and Safari on iphone4s(ios7.0.3) have issue with wiki of mavericks server.

(can not access first page of wiki project, but it is available access created contents)

And finally, webmail is not working while IMAP is working.

(can not access webmail on browser by used domain address)

but, address book and file share is ok.

and new add calendar is working well.

- not test another services on mavericks server.
