We're in the process of migrating an outdated e-commerce cart to Magento. Part of this process will entail configuring proper 301 redirects. I'm aiming to get a list of all indexed pages to throw our solution against and resolve as many potential issues as possible before going live.
Ideally I'd just need a CSV containing the URIs indexed by the Search Engines for our domain.
Looking at a similar question here, it seems there is no simple way to export this data from either Google or Bing's Webmaster tools, given that this cart has tens of thousands of products (and thus tens of thousands of indexed pages).
I've run across a few other 3rd party utilities such as Screaming Frog and web-based ones like searchenginegenie and internetmarketingninjas, but I've never used any of them and am hesitant to start throwing additional traffic at our site unless I know we'll get what we need out of it.
Has anyone out there used these tools to do something similar, or found some way to retrieve more than the top 1000 records from GWT (or something similar from Bing)?
