      Our marketing department has decided that a new site with new content is needed to launch new products and support our existing ones. We cannot use the same subdomain(www = old subdomain  and ww1 = new subdomain)as there is a technically clash between the windows server currently used, and the lamp stack required to run the new wordpress based CMS and site. We also have an aging piece of SAAS software on the www domain which is makes moving it to it's own subdomain far too risky.

      301's have been floated as a way of managing the transition. I'm not too keen on that idea due to the double effect of new subdomain and content, and the SEO impact it might have. I've suggested uploading the new site to the new subdomain while leaving the old site in place. Then gradually migrating sections over before turning parts of the old site off and using a 301 at that point to finalise the move.

      The old site would inform user's there is a new version and it would then convert them to the new site(along with a cookie to auto redirect them in future.) while still leaving the old content in place for existing search traffic, bookmarks and visitors via static URLs.

      Before turning off sections on the old site we would create rel canonicals to redirect to the new pages based on a a mapped set of URLs(this in itself concerns me as the rel canonical is essentially linking to different content).

      Would be grateful for any advice on whether this strategy is flawed or whether another strategy might be more suitable?

        Patrick is right, the migration guide is an excellent source to make sure you've covered all the bases.  That said, setting up 301 redirects is gonna have to happen.  It may hurt, it may take a lot of time, but it's the best way I've found to minimize any negative impacts to rankings and traffic.  There are, of course, ways to speed this up, but I wouldn't suggest looking for a work-around.  It sucks to do but that's why new sites and new content on new domains can be such a nightmare.

        It's mind-numbing as a task but your manager/client will be very impressed by it.  Make sure to look over the inbound links to your site to ensure no pages are missed thereby breaking some of your link network.

          Hi there

          I would run through this migration guide step by step as it is quite comprehensive and can definitely help in making this as seamless as possible.

          Hope this helps! Good luck!

            Removed Subdomain Sites Still in Google Index

            Hey guys, I've got kind of a strange situation going on and I can't seem to find it addressed anywhere.  I have a site that at one point had several development sites set up at subdomains.  Those sites have since launched on their own domains, but the subdomain sites are still showing up in the Google index.  However, if you look at the cached version of pages on these non-existent subdomains, it lists the NEW url, not the dev one in the little blurb that says "This is Google's cached version of www.correcturl.com."  Clearly Google recognizes that the content resides at the new location, so how come the old pages are still in the index?  Attempting to visit one of them gives a "Server Not Found" error, so they are definitely gone. This is happening to a couple of sites, one that was launched over a year ago so it doesn't appear to be a "wait and see" solution. Any suggestions would be a huge help.  Thanks!!

            How to create site map for large site (ecommerce type) that has 1000's if not 100,000 of pages.

            I know this is kind of a newbie question but I am having an amazing amount of trouble creating a sitemap for our site Bestride.com.  We just did a complete redesign (look and feel, functionality, the works) and now I am trying to create a site map.  Most of the generators I have used "break" after reaching some number of pages.  I am at a loss as to how to create the sitemap.  Any help would be greatly appreciated! Thanks

            404 Errors After Site Migration

            Hello - I'm working on a website selling fashion accessories.  The site just went through a site migration from Yahoo! to Big Commerce.  Now we have a high level of warnings and errors from the crawl.  Few are mentioning sites I never seen before on the Yahoo! platform. I also notice that the pages crawled has doubled.  How can I fix or did I do something wrong with migration? I was running the website with minimal errors and now overwhelmed with errors all the error updates.  If I can get some assistance on what could be wrong, I would greatly appreciate. Thanks.

            Redirecting Entire Microsite Content to Main Site Internal Pages?

            I am currently working on improving site authority for a client site. The main site has significant authority, but I have learned that the company owns several other resource-focused microsites which are stagnant, but which have accrued significant page authority of their own (thought still less than the main site). Realizing the fault in housing good content on a microsite rather than the main site, my thought is that I can redirect the content of the microsites to internal pages on the main site as a "Resources" section. I am wondering a: if this is a good idea and b: the best way to transfer site authority from these microsites. I am also wondering how to organize the content and if, for example, an entire microsite domain (e.g. microsite.com) should in fact be redirected to internal resource pages (e.g. mainsite.com/resources). Any input would be greatly appreciated!

            Content loc and player log tags for XML video site maps

            I need a little help understanding how to create two of the required tags for a XML video  site map for Google. 1. video:content_loc2.<video:player_loc< p=""></video:player_loc<></video:content_loc> Google explains their Video XML Site map requirements here:
            www.google.com/support/webmasters/bin/answer.py?answer=80472
            Using the example on this Google Web Master Help page (where they explain all six of the required tags) , here are examples of the two  tags I need help with: video:content_locwww.example.com/video123.flv</video:content_loc> <video:player_loc allow_embed="yes" autoplay="ap=1">www.example.com/videoplayer.swf?video=12...video:player_loc></video:player_loc> The video I am trying to optimize is located on a page on my site:
            www.mountainbikingmaine.com/races/bradbury_hawk.html
            This page has an embedded Vimeo video. So I don't have the video file on my domain. It is on Vimeo. Here is source code from my page that I think provides the information I need to create the two tags that Google requires. <iframe src="<a rel=" nofollow"="" href="http://player.vimeo.com/video/24580638?title=0&byline=0&portrait=0"" target="_blank">player.vimeo.com/video/24580638?title=0&...amp;portrait=0"</a> width="400" height="533" frameborder="0"></iframe> [vimeo.com/24580638">Bradbury](<a rel=) Mountain Maine Hawk Migration Count from [vimeo.com/user3219915">dan](<a rel=) sexton Using this source from my site, can you suggest what to put in the two tags? Thanks! Dan
