Looking to hire someone to help convert a 5.6.3.4 site to 5.7 platform. I have tried the github migration tools and they are failing on the customized theme that I inherited from another company. I'm able to get the old theme installed in 5.7, but I'm struggling with the format. Don't know enough about Concrete5 to know what or how to move all the custom items (blocks, stacks, packages), or if I even need to. Please private message me your contact information if interested. Thanks in advance for your help.
