Search links pointing to old pages - Joomla! Forum - community, help and support

joomla green-horn here. had consulting company re-configure our website using joomla! on our new web server. our old server/website using old content manager setup consultant years ago before time.
we having problems search engine results - results pointing pages in old format not exist on new joomla! site. domain , structure same page links use "page1.aspx", joomla article pointers "index.php?option=com_content&view=article&id=52".
how correct these search results? should have been done on new joomla site.

thanks in advance

unless archival files need posted, should let
google remove them. may quicken process trying test link,
but counterproductive. google automatically its
spider. see:

there nothing in joomla eliminate listing on google of obsolete pages.
my experience 2-3 weeks, gone and/or new pages show up
in front of old pages. want use seo , optimization new pages indexed , rated.
