Scaling 32 bit ASP.NET Application to a 64 bit OS Platform | Mailbag Discussion

Well, its time for some discussion. Few minutes back, one of the reader ‘Om’ had asked this below question –

“I’ve small query related to application compatibility. We have a SaaS based product hosted on group of windows 2003 server standard edition (32bit). To scale up further we upgraded RAM of few systems to 8GB from 4GB. But since 32-bit version of windows 2003 does not support more than 4 GB of RAM , we have to switch to different edition. Now we have the option of either trying 32-bit Datacenter edition(cost around 3000 bucks per system per month extra by our host provider). or 64 bit Standard edition (with no extra cost).

So my query is that how much effort is needed (if any) in migrating a 32 bit application to a 64 bit OS platform? Apart from app we have bunch of WCF services?”
