Replication in clustering

Hello,

I am upgrading from SQL 2008 R2 SE to SQL 2012 SE. I am backing up databases, scripting out logins, linked servers and sql agent jobs. However I plan on detach and attach the databases.

Also, I have a transaction replication setup in sql 2008 r2 with subscriber and publisher and distribution on the same server. How do I move this setup after I upgrade to SQL 2012 SE?

Any steps that I shd follow are highly appreciated.

Thanks a bunch in advance
