I'm a newbie and today I upgraded (sidegraded?) from Vue 8 Esprit to Vue 9 Studio. I got Vue 9 installed, but I have a question about handling the new content. With Poser having multiple runtimes is no problem, and even good.  How about with Vue?  Should I move all by purchased Vue 8 content to the Vue 9 folder? Before I start shuffling content folder I need some advice. When you upgrade, how do you handle the content from the prior version?

First of all:
1 - any Vue version reads older version files but can't read files saved by newer versions (e.g. v9 will read your v8 content but won't read v10 content);
2 - any Vue version writes files using it's specific version (you cannot tell v9 to create v8 compatible files).

To sum up, you go forward without problems but cannot go backward.

When I get a new version, I keep the old one on line for some time until I am rock sure that the new one is better; during this transition period, I keep separate directories for the different versions of files (e.g. a material directory called Own with a 9 and and a 9.5 directories in it until I remove v.9).

Content developers keep installed different versions of Vue to be able to save the different versions of files (you can have as many Vue versions installed as you like, just be careful of what you use).

Hope that it was clear, otherwise keep pestering.

So until I've had a chance to throughly check out V9 I should keep my V8 directory as is? But I can access the V8 content with V9. But if let's say I open a V8 spacecraft in V9, will it change the file so I can no longer use it in V8?

Changes happen only when you save with the new version. If, for example, you just open and render, the old content remains compatible with the old version.

You can use the object within a scene saved as a Vue 9 scene file, the original object will still be readable by Vue8. It's only if you resave the object (as a vob, not a Vue scene file) in Vue9 that it won't be compatible with Vue8 anymore.

Thanks! That makes a big difference. I always save the scene while I am working on it so it's good to know that won't modify the object file.
