What is the difference between Legacy Software and the Next Generation of ERP?

When we say Legacy software, we are typically referring to offline ERPs. They are also called on-premises ERP systems. On the contrary, the Next Generation of ERP is nothing but a cloud-based ERP tool.

Let us analyse the difference between the two further:

The cloud ERP offers greater ease of access compared to the Legacy ERP. Using the Legacy ERPs, you will have to maintain the ERPs on your server or computer. The people who have the authority to use the ERP can only gain access through the machine. Since the Next Generation ERPs are present on an internet server that you own or lease, you require a web browser to access it. You can access it using any web browser like Chrome, Safari, and Edge.

The Next Generation ERPs are futuristic. It incorporates technologies like the Internet of Things (IoT), artificial intelligence, big-data analytics, machine learning, and cloud computing. The core functionalities of ERP are well defined to the vertical industries that it serves. We can say that these ERPs are based on software as a Service or SaaS. This implies that you must pay a fee to get permission to use the software and hardware on which it operates.

It is easier to update and customize the Next Generation ERPs compared to Legacy software. The changes can be made automatically. On the contrary, Legacy software ERPs might be tough to change with limited knowledge. You require a robust IT team for this.

You can use any device with the internet to access the Next Generation ERP systems. Your only requirement is a web browser. For Legacy ERP, you need a machine with the software enabled.

Modernizing The ERP Cloud

Modernizing your ERP through ERP cloud poses plenty of advantages that can help optimize your business’s processes. Let us see how:

The security on the cloud is high for outstanding data use and integration. Some cloud services offer automatic encryption of the stored data. This takes the stress off the IT department.

The feature of the cloud’s data scalability can ensure the storage easily scales based on changing demands.

The cloud is always functioning. You can instantly access the applications and data in the cloud. You can also access it via any device. The updates and software installations also occur with minimal intrusion into the team’s workload. In terms of data migration also, the cloud offers a simple process.

With ERP cloud, the vendor is responsible for the full maintenance. The data hosting is handled well, and they also maintain hardware to run ERP services. All this makes things easy for the company’s IT team.

With the cloud, downtimes rarely happen. This is due to the intricate architecture of the cloud and its perpetual on-capability feature. Yet, if the cloud goes down at some point, you can also use local servers as a backup.

What are ERP Upgrade Benefits?

For those who use Legacy ERP systems, it is crucial to upgrade them to salvage the benefits compared to those who use cloud-based ERP.

The upgrade is prime because it helps receive updates, new features, service packs, and much more. All of this is in real-time. A system that is up to date will be optimized. Through this, your workers do not have to stress about the downtime.

Doing the upgrade for AS400 ERP without any business disruptions will ensure you get the most out of cloud ERP.
