how to 3.7.94 to 3.4.02

SojaLin

Hello, because of the need for project maintenance,
I have to downgrade the SPINE I made from version 3.7.94 to 3.4.02.
I have found many methods on the Internet,
and there are almost no articles about the method of downgrading from 3.8 to 3.7 and 3.7 to 3.4.

I export the SPINE of 3.7 to JSON so that 3.6 can read it
3.6 Exported again, trying to get 3.5 to read but failed

Would like to ask how to downgrade SPINE version 3.7 to 3.4 or 3.3?

Thank you and have a nice day

SojaLin You will need to use the JsonRollback tool. The following thread would be helpful for you:

Unfortunately, you cannot downgrade from 3.7 to 3.4 at once, so you have to go through the steps of downgrading the 3.7 project to 3.6, 3.6 to 3.5, and so on, as you have tried.
