Inquiries about upgrade issues

[MrGongqi]

Hello, I have been using version 1.3.0.0 for almost a year and it is really great, thank you for your efforts. Now that I see that you have added the new version, I would like to experience what sublimation functions are available, but I have a difficulty, that is, I cannot upgrade on the existing 1.3.0.0, which means I have to download 1.4 again. Does it mean that I have to re-establish synchronization? I already have more than 100G of content connected through 1.3.0.0. Re-establishing these synchronizations requires a lot of effort.
