On the Laravel News site they've posted a tutorial by Joe Ferguson showing you how to [use older versions of Homestead](https://laravel-news.com/using-older-versions-of-homestead, the box not the app, in your development environment if there's a need.
There are two parts to Homestead: the Vagrant box and the Homestead source code (Homestead app). The Homestead Vagrant box is a snapshot of a preconfigured virtual machine ready to use. [...] We use the Laravel Settler repo to build the Homestead boxes. You have to ensure the version of the Homestead Vagrant box is compatible with the version of the Homestead app you are using.
Why would you want to use a previous version? [...] While Homestead development moves forward pretty quickly, you may not be ready to move your clients from PHP 5.5. While you should have already moved your apps to PHP 7.0 for the performance gains, I understand that because Laravel 5.1 supports 5.5, developers may want to continue using that version.
He then walks you through an example, showing how to use PHP 5.5 with Homestead and what version to put for the best support. It requires a little bit of manual fiddling around but not too much. Then it's just a simple "vagrant up" to get it running. He also includes instructions on using PHP 7.0, checking out a different version of the Homestead repository and bringing up the box similar to above.
