*’Lift & Shift’ approach may work at some places, but you’ll have to plan data modelling and routine setting leveraging automation to encompass the migration procedure

Step 5

Cloud migration checklist will assist you to ensure that you follow a strategical plan and you are ready for all the possible issues that might come up which will help you to avoid challenges and ensure a smooth journey.
