The greatest success is quite honestly, the demise of the upgrade cycle. You are not making colossal, dreadful version switches every five years with a system of ERP SaaS solution in the clouds. The provider sends small updates progressively. You are never behind any update and do not have to spend a weekend waiting to find out the latest version like the old system. It completely changes the game of the sanity of the IT team.
Oh sure, keep the legacy ERP. Personally I enjoy spending my Sunday mornings in a cold server room praying that the database will finish its re-create due to power flicker. Why sleep or social life when you can be able to patch 15 years old software by hand and it only works with Windows Server 2012? Certainly, keep it with the dinosaur of technology; it is fabulous in building the character.
You have to put this in the form of CAPEX vs. OPEX as the leadership. The cost of running legacy systems involves high initial investment in hardware and license depreciation. A SaaS model switches that to an estimated operating cost. In addition, the security measures of a large cloud provider data center are likely to be far stronger than what your local IT store can be keeping on-site.
My current ERP is so ancient that it hasn’t realized that Macarena is no longer a new dance. Moving to the cloud was the same as riding a horse and a carriage to a Tesla. There will be no more excuses of the server being down when one is at home trying to log into the system. All you need is a good internet connection or you will be looking at a wheel of death.
I will act as the devil: You are selling convenience against control. In case the SaaS vendor goes offline, your whole business simply comes to a halt and you can do nothing but wait until they post a status tweet. In legacy, a failure at least provides you with the ability to poke the hardware yourself. It was just something to remember.
It is actually the scalability that sells. Suppose your company doubles its size in a year, a cloud system simply readjusts your bill. In your previous system, you would have been placing new rack orders, recruiting more sysadmins and curled up sobbing at the procurement invoices. Go cloud and don't look back.
The immigration will be a nightmare I shall not tell you otherwise. Decommissioning of an old system is comparable to cleaning a basement that was not opened since 1998. But when you are over on the other side? The fact that one does not ever have to worry about hardware refresh again is worth all the headaches during the transition.
It is not only the cost of the parts it is the knowledge of the tribal nature of the maintenance of the old systems. You are likely to have one of those men who knows how the entire sham operates and when he retires, it is all over with you. The current standards that are employed in the SaaS systems are much easier to train new employees on.
Wait, we are still using on-prem ERPs in 2026? It is like sending a text message using a rotary phone. And unless it is a government bunkhouse secret facility with zero internet connectivity, there is no logical justification to remain on legacy. The subscription is compensated by the maintenance savings in two years.
Target the factor of accessibility. Your employees desire to be mobile on their tablets and phones, and not have to be chained to a desktop in your office through a stuttering VPN. Cloud-based system implies that your data is everywhere your employees go. It is not saving a few dollars on server components, but rather it is about productivity.
