I will provide a days remote consultancy to Migrate data from a File Share to SharePoint / OneDrive for Business.
If you purchase one day it will be a cold and dirty lift and shift, this is NOT the way to do it but you won't be the first to take this approach, as a general rule of thumb 100GB of data "could" be moved in 5-10 days including some general prep and a decent site structure setting up.
I have been part of projects that have taken anywhere from 2 weeks to 6 months to complete depending on the complexity.
Previous clients include but are not limited to: NHS, Department for Education, Oil & Gas group of companies, Natural Resources Wales (Welsh Government)
Additional days can be added below with expenses added for onsite work
