I haven't been able to find any data that indicates this can in fact be done but the historical data does have some value to us. Has anyone executed this successfully and would you be interested in a 'consulting' engagement via freelancer?
Hi,
This sounds as a fun project to do. I have migrated our system from on-premise Windows with an old WHD and PostgreSQL 9 to a Linux server in Azure and the latest WHD and PostgreSQL 13 in one go about a year ago. If I were you I would start with a dump/copy of your existing data in a development environment.The PostgeSQL website has information on the supported conversions: Converting from other Databases to PostgreSQL - PostgreSQL wiki
Which SQL database are you running now?
Are you running WHD on Windows or Linux?
Best regards,
Arjan
