Hi friend. You are top coder for vtiger so
You can upgrade a vtiger System from 5.1 to 5.4?
Amount database is 230MB ( May be it is about 40k records at Leads, COntact and Account as well as Product modules)?
What is your plan and solution? How can you do? You can make a good plan for me. If ok, we can work for a long time/ I need a maintain programmer.
