Migration from CentOS 5 - 32bit to CentOS 6 - 64bit?

I have recently noticed my mail inbox and come to know that Webfaction is offering to migrate from CentOS5-32bit to CentOS6-64bit(has latest version of mysql and postgresql). So, I have following queries:

What are the advantages or probable disadvantages(if any)? ie. performance, security ..etc
I have a codeigniter app, a punbb forum, a wordpress blog and an OSQA application and 2 awstats apps. So if I want to migrate to CentOS6, then which of above applications will be affected or all of above will work properly and if there a timeout, how much time will it take.
How to do this migration, I am not familiar with this migration stuff. If webfaction does it for me then Is there any actions which I have to take on my part?

Thanks !!

Hi,

What are the advantages or probable disadvantages(if any)? ie. performance, security ..etc

CentOS 6 is the newest operating system we are offering as such it has the latest updates and packages like MySQL 5.5 and Postgres 9.1.

I have a codeigniter app, a punbb forum, a wordpress blog and an OSQA application and 2 awstats apps. So if I want to migrate to CentOS6, then which of above applications will be affected or all of above will work properly and if there a timeout, how much time will it take.

All the PHP apps and Awstats should work without problems.

You may need to follow: http://docs.webfaction.com/user-guide/moving.html#django

for your OSQA app since it is based on Django.

Are there any performance differences between sites on CentOS 5 and CentOS 6 in webfaction's server setup? Can I expect my sites to be any faster (or slower)? What are the differences in memory consumption?

You should expect better performance because the cgroups kernel feature will fairly allocate resource to all users on the server. You might see higher memory usage since 64-bit apps generally use a bit more memory, but I don't know exactly how much.
