Welcome to the Q&A Forum

Hey, Unfortunately this would not be possible (especially as we recently released a new index which changed how DA/PA was calculated, therefore you wouldn't be able to compare against previous results). You can see history for DA for near enough the past year in Link Explorer. We have a great guide on it here: https://moz.com/help/link-explorer Let me know if you have any other questions and I'll be more than happy to help! Have a great day! ​Eli

Hi Jennifer, Considering that you tackle everything needed in a migration (such as proper 301 redirects, new sitemaps and all that).. What you should spect in an organic traffic perspective: Rankings will vary for some days while google is understanding the new site, hopefully wont take longer than a month. Visits could be down for the time where rankings are fluctuating Google will show both site in SERPs for some time Keep in mind that this is a migration, like any other. So it could come handy these resources: The Website Migration Guide: SEO Strategy, Process, & Checklist - Moz Blog The Ultimate SEO Guide for Successful Web Migrations at #DigitalOlympus - AleydaSolis Migration Best Practices - SMX London 2018 <- backedup by JohnMu in this tweet Hope it helps. Best luck. GR

Hey there! We'd recommend checking out this resource page to learn about Spam Score and its applications: https://moz.com/help/guides/link-explorer/spam-score As for why you might not have a Spam score yet, it is determined by a separate crawler than the crawler that powers Link Explorer and updates roughly once a month. Because of this, it is entirely possible to see backlinks and domain authority, but still have no calculated Spam Score. As we continue to crawl and calculate sites, this will become less of an issue, but unfortunately at this time, we will need to wait for the Spam Score user-agent to find your domain. Hope that helps!
