Moving published database from SQL 2005 Std. version to SQL 2012 Std.

Hello, 

I have  a published database 'foo' in production on SQL Server 2005 Standard. It serves 2 subscribers which use SQL Express version for subscription.

Now I want to detach that database 'foo' from old server and attach to new SQL Server 2012 Standard.

Can I shift my old database to new server as it is? I know that I won't be able to detach database if its publishing...

but if I drop articles from current publication,

Can I keep my old  replication settings intact while moving to new server?

Will I have to create new publisher and subscribers?
