When bandwidth limit increases then domain shift to another domain which is no index. As website ranking is decreases and google is not fetching data as in website mata and in contetn, so I think it may be the reason of shifting urls or some other reason? Can any one guides me?
LIke a site www.rozee.pk is when its bandwidth limit increases it will be shifted to us.rozee.pk. As we did this google drop down ranking and also not fetching data from main domain www.rozee.pk
It may be your transferring data problem. You didn't transfer your website data to a new domain according to the guidelines of Google. So that is why it happened according to the info that you have provided in the question.
Well I have searched and come to know that Google is crawling website but not indexing. As last time google index home page dated 31.03.2013 and now 13 days passed but Google haven't indexed yet.
to google those are two unique sites, so one may get indexed and rank #1 the other may never get indexed. Google ranks webpages not websites. So you have to optimize both as different.
Since keywords hold the key importance in google ranking, and its also important to do a keyword research before to start any SEO campaign.
