As a Serif user since 1989 I have regularly updated my PagePlus versions but this latest release will only be of any use to new customers. Your existing customer base will not switch if it is not provided with a conversion tool to import older files. The suggestion to export as a PDF from the old files is not a practical solution. I have hundreds of client files created with PagePlus9 or earlier that I can't afford to lose, but neither do I want to learn how to use another piece of software if it can only be used for new work. Remembering which program was used for which bit of work will become a nightmare over time. A crossover routine is a must for Affinity Designer to be a no-brainer upgrade. In trying to be modern don't isolate a multi million user base that has taken time to create.
