Down grading from 8.6 to 8.5

[Tuesday]

For reasons I won't bore you with, I need to down grade my labview version from 8.6 to 8.5.  But when I upgraded to 8.6 originally all my vi's updated as well.  How can I open the now saved as 8.6 vi's in 8.5? I do have more than one computer...

Just open the VIs in 8.6 and select File -> Save for Previous Version. If you start with the top-level VI, then all the subVI will be saved in 8.5 as well.

Nifty! Thank you.

Hi Tuesday,

the other, easier solution is to pick up your LV8.5 backup that you surely made before upgrading (and of course in regular intervals...)

I know you weren't making an entirely serious reply.  But just out of curiosity; how would one "backup" one's previous LV installation?  

So many files are updated and changed during the process, that I would think nothing short of a full hard drive clone would work as a "backup".   

If there's an easier/slicker way, I'd love to hear about it.  

Until then,  Clonezilla is my friend.

Hi Patrick,

I wasn't referring to a backup of the LabVIEW installation, instead I meant the backup of the vi sources!

To install (even older versions of) LabView again is just some nasty work of hours. But to recode your vis again will take months - so you should backup your own development folders on a regular basis. And additionally backup out-of-order when upgrading LabView...

With a free source code control program such as TortoiseSVN available, there is absolutely no reason to use that to store each and every version of a VI. Doing a regular backup of the repository is also simple and doubly protects you. Any serious programmer (LabVIEW or otherwise), should be operating this way.

I don't know if you already realize this but when you install a new version of LabVIEW on your computer it gets installed to an entirely new folder in the National Instruments directory of your program files folder (in windows). This is means you can still use the older versions without having to reinstall by just running those verisons. But yea, you will have to open any VIs you saved in 8.6 and do the 'save for previous version' thing to be able to open them in 8.5.
