SAP? An alternative to this strategy might be to have your own software team that builds tools and processes for you to "work with" or "work around" your primary software without fully replacing it. As others have mentioned, what you want is achievable, if managed the right way, with the migration done in stages.( Trying to replace the whole thing in one jump would be very risky.) In the real world though its quite easy to miss requirements, some quirk of the existing software nobody really thinks is a feature, except that one person in the office who has gotten used to abusing that quirk to achieve a task. There is also possibly a lot of domain knowledge that the software team you hire might not be versed in, which can be tricky, although this is partially solved by having a good project lead and strong communication between the teams (software and non-software) Where is might get more tricky is if you to adhere to certain ISO/etc certifications.
