Hello :)
As a new administrator at my company I would like to upgrade old mediawiki to the latest one, but I'm not sure if it is possible at all :)
Current one -- Debian 7.10 / PostgreSQL 9.4 / MediaWiki 1.15.1
The new -- CentOS 7 / MariaDB / MediaWiki. All up-to-dates :)
The OS's is no problem. If it is not possible to do the seamly migrate from pgsql to mariadb it's fine, let it be postgresql. What about ofupgrading 8 years old MediaWiki? Is it worth? If not, what about data from the old one? What is the best way to do the migration job?
The MediaWiki users are from AD by the LDAPAuthorization backend, and we use extensions: SyntaxHighlight (broken now after some problem with old server), Calenda, FCKeditor, FileProtocolsLinks, NewestPages, WhitelistedNamespaces and Multilang.
I will be grateful for any help :)
Regards.
