I'm migrating Alfresco Community 4.0.b from Server 1 to Server 2. Both are Ubuntu Server 10.04. I have followed the instruction from wiki, and I used binary installation file to install Alfresco on both server.
Database back up and restore code:
pg_dump -U postgres -h localhost -p 5432 -F c -v -f alfresco_db alfresco
pg_restore -U postgres -h localhost -p 5432 -C -d postgres -v alfresco_db
When starting Alfresco on Server 2, I get this following error:
2012-08-07 07:50:15,623 ERROR [web.context.ContextLoader] [main] Context initialization failed

What's missing?
Edited.
I've found the solution!
After copying alf_data to Server 2, I need to delete the SOLR index data and start with SOLR rebuilding the index.
Everytime when I'm doing migration, I made this:
- pgDump & restore
- copy contentStore & contentStore.deleted
- full re-index
While I'm talking about postgres- there are 2 ways how to dump and restore.
compress dump:
pg_dump -Fc -U <DBUSER> <DBSCHEMA> > <fileName>.sql.Fc
pg_restore -U <DBUSER> -d <DBSCHEMA> <fileName>.sql.Fc
plain txt/sql:
pg_dump dbname > outfile
psql dbname < infile
For copy files no comment need :o)
And for re-index SOLR- that works
