Wiki migration from Mavericks to Yosemite Server

Hi all,

I'm migrating a wiki server from 10.9.5 with Sever 3.2.2 to 10.10.1 with Server 4.0.

i've done these steps :

- backup postgres database with :

/pg_dump -h "/Library/Server/Wiki/PostgresSocket" --format=c --compress=9 --blobs --username=collab --file=/Volumes/ServerHD/Users/admin/Desktop/collab.pgdump collab

Then on the Yosemite server, i've retore the wiki database:

First, in postgres :

psql -h "/Library/Server/Wiki/PostgresSocket" -U collab template1

template1=# SELECT pg_terminate_backend(pg_stat_activity.pid) FROM pg_stat_activity WHERE pg_stat_activity.datname = 'collab' AND pid <> pg_backend_pid();drop database "collab";create database "collab";

- then restore postgres database with :

pg_restore -h "/Library/Server/Wiki/PostgresSocket" -d collab -U collab --single-transaction /Volumes/ServerHD/Users/admin/Desktop/collab.pgdump

I've transfered FileData folder between the two servers, and fix rights via chown -R _teamsserver:_teamsserver for the FileData folder in /Library/Server/Wiki/

After that, i used two commands :

wikiadmin fixPermissions

wikiadmin resetQuicklooks

All the wikis are visible, and seems to work fine.

But, when i try to view or download an attached file from a wiki, server returns an error page indicating that wiki is not activated (!!??)

I think there's a new organisation for the attachments in the wiki part of Yosemite, but without any documentation, it's not easy to make it work.

Does anybody got this problem a have a solution?

Thanks a lot

Bertrand.
