I am using Google webmaster tools for my site. I recently have changed address. Now, I wonder why the number of indexed pages in Crawl -> Sitemaps and Google Index -> Index Status are different?
Hope anyone can help me.
Keep calm. There are many different caches, datacenters, and latencies in the Google indexing system. If your new domain is set up properly and the whole site (including the sitemap) is available for the bot, you'll eventually see the correct numbers. It can take up to three months.
I just saw that the Google Index Status report has been broken for the last weeks or months. It hasn't been getting any new data.
Google just announced (Friday, Aug 26, 2016) that they fixed it. Your report will start showing more indexed pages if it hasn't already done so.
