SEO help related to content and domain migration

[shaunm]

Hi All,

Website migration related SEO is new for me. I have a situation that where the ASP pages in a website are going to get covnerted to ASPX. I am not sure of the difference between this two close technologies.

So, once the pages are converted they will still reside in the same domain. But in a week, this converted pages will be migrated to an ASPX domain (a completely different domain)

This is what I am thinking of from the SEO point of view. Your suggestion on this will really help me a lot in the process. Thanks in advance.

Phase 1: ASP to ASPX (Same domain)
SEO suggestion - Put a 302 redirect

Phase 2: Domain to Domain migration
SEO suggestion - Remove the 302 and put a 301 redirect.

Is this the correct process?

My concerns are:
1. The current website has more than 2000 ASP pages that are indexed by Google. When I put the 302 redirect as per the Phase1, will that get any negative impact?
2. The time range between the 'content conversion' and 'domain migration' is 3 weeks. Will Google replace the ASP pages in its index with ASPX pages before the domain migration happens? In that case should I block those pages using Robots? And when I put a 301 redirect, will that again replace the ASPX pages with the new domain destination? Is that going to help me or do harm?

Thanks for your expertise answers :-)

Three weeks? Make only one change, not two. Use only a 301 redirect to the new domain, on a URL by URL basis. Good luck with the IIS server ;)

Just to be sure when you say domain you do mean a different "domain name" and not just a different host?

If that is the case you may as well just 301 the asp pages to the the new domain where the aspx resides, as tedster suggests.

Otherwise you can use DNS to migrate, (and use 301 either before or after, not sure what would be best scenario in this case)

slowly, slowly.

@Tedster
Thanks for stopping by :-)
The developers are converting the pages from ASP to ASPX. Once it's done, the domain along with the converted pages will be moved to a new domain; from abc.com to xyz.com.

Should I just wait till the domain migration happens and put only one redirect which is 301 in place? Then what about the pages that go through a conversion process? Should I stop them from getting live before the domain migration happens? And I failed to stop the new ASPX pages getting live, will using 302 redirect works?

And yes, I wish the developers a good luch with the IIS server :-)

Thanks!

It's domain abc.com to xyz.com and both the domains are residing in our own server.

Thank you both again :-)
