I am currently running TrustedLink 5.2. I am on an AS/400. I need to get to 5.4 but need to go through 5.3. Inovis is suggested to do two upgrades at once. This is too time consuming for my company. I want to go to 5.3 and a week or so later migrate to 5.4. Has anybody run 5.3 successfully from the 400 for a period of time? I want to make sure I don't impact the business using 5.3. Thanks in advance.
