From: Jack Hutton, RE: IT Infrastructure Update Hi, Over the next couple of months there will be an IT infrastructure update. We're looking to replace all infrastructure that is over 3 years old. Currently we have a budget of 200,000 set aside for this, do you have any concerns with this? Select an option below to reply. The total cost to replace all infrastructure is 4,346.50 under budget, so we could make even more replacements. The total cost to replace the infrastructure is 4,970.50 under budget, so we could make even more replacements. The total cost to replace the infrastructure is 6,300.00 over budget, so we should rethink what's being replaced. The total cost to replace the infrastructure is 43,574.10 over budget, so we should rethink what's being replaced
