I just found out that my company is planning to acquire more firms, and they want to cut back on migration costs by eliminating contractor help. Instead, they plan on giving us a budget to purchase our own migration tools. While I think we can handle this ourselves, it seems like it will take a lot of time, especially with these quick acquisitions. I'm even updating my resume just in case it all becomes too overwhelming. What tools and resources have you used for migrating companies into yours, particularly since we use Office 365 with a heavy reliance on SharePoint?

I highly recommend checking out the Quest suite of tools. I've used them extensively, handling over 400 integrations myself. They're pretty reliable and efficient for migrations.
I second the Quest On Demand recommendation—it's been my go-to for about two years during our mergers and acquisitions.
Consider using AvePoint Fly for SaaS migrations; the pricing is pretty low per user, and it offers dynamic mappings. Just be warned, purchasing directly can be tricky since they mainly sell through CSP partners. For migrating traditional file shares to SharePoint, we've been using the Microsoft SharePoint Migration Tool with some manual cleanup before migration.
BitTitan and ShareGate are solid choices we’ve used in our migrations. Just a heads-up though: not involving contractors might backfire on your company. Handling migrations internally can be time-consuming and there are often small, critical details you might overlook, which could lead to issues down the line.

I’d add ShareGate and MigrationWiz to that list. Also, have a look at this resource: [thecloudgeezer.com link]. His discovery tool is a total steal! Honestly, dropping the contractors could be a mistake; they've got the experience to handle what might go wrong during these migrations.
