Don't know anything about Infor but these are huge complex systems that people don't want to change because there is a huge risk of changes. So now they are falling behind, running up huge amounts of technical debt, and staying on old systems. I know with SAP most people have never heard of HANA and most of the companies that migrated did so because they were on very very old versions. Oracle EBS is pushing this migration to the cloud that is making a bit of traction with SMBs but not going anywhere in the enterprise and changes are difficult.
