Hi I ,stiil, build my website on localhost on platform of osclass Evo 4.4, sadenly I saw that there is v8.0.2. Is it a continuation of Evo 4.4 or are another developers? And if 8.0.2 better than Evo 4.4 how safely update it who knows?! Thanks for helping good people...

Use Osclasspoint 8.0.2. 
+ osclasspoint plugins & themes compatibility
+ best themes and plugins
+ super active developer
+ pro support
+ updates

Evo 4.4.0 version
- last update 14 Feb 2021
- I think, it is a death project
- no updates, no new plugins, no new themes, no support

Evo is dead, no development anymore (1 and half year) including products in their market - without updates.

I agree Osclasspoint 8.0.2 is the best....

Ok. thanks so how I can to update my project (in local host) from Evo 4.4 to 8.0.2 without lost something from my project?

@Newbie
I do not think there would be some issues upgrading, but better to create copy and try update on test site first.

Thanks.

I tried to update from TOOLS > UPGRATE.. but the script write to me something like that "you have the best osclass version you don't need to update it" what to do?

You must upgrade manually
