Software Version

[[Ra...]]

Dear Friends,

We have multiple CMM machines with 6.2 Calypso Software version.
I am thinking to upgrade one of my CMM to 2018(6.6) version.
My question is after making new measurement plan in 6.6 version,
Can I open and edit same 6.6 version plan with 6.2 version CMM ?

Anyone did this or have some information, Please advice.

Thanks.

As with pretty much all software, no Calypso is not forwards compatible, though I have not specifically tried this with the versions you specify, however I am fairly certain it will not work.

For some reason the Software engineers seem to have trouble seeing into the future.

So no you cannot open a 6.6 program using 6.2 and have it work correctly.

The question was not whether a 6.2 program was able to be opened with 6.6, it was whether a 6.6 program could be opened with 6.2.


It is certainly possible to open older programs with the newer software, once in while you may run into a problem but it is usually pretty reliable.

I am incredulous at the possibility of opening a newer program with an older version of calypso?

I would have to see this to believe it, and even then I can not fathom why anyone would want to, as the older software would not be able to interpret the newer functionality in the newer program and would need to ignore it which would lose functionality.

As a mode of working, we don't recommend that a user should count on being able to move backwards on a measurement plan. The ability at one time or in certain circumstance to move backwards with or without manual intervention has its limitations. If the intent is to keep versioning positioned at say 6.2 for production, but begin to use 6.6 for validation reasons, I recommend leaving 6.2 also on the PC that is planned for upgrade and testing. We have allowed parallel installations since at least 5.6. All edits for the production machines should then be done in the earlier release.

I would also recommend that before experimenting with the migration, you make a back up of your inspection plans to archive them in the 6.2 revision. Data storage mediums are considerably less expensive than the effort and time (and frustration) it would take to recreate measurement plans or the downtime it might take before a purchasing agent can get the approval for a software upgrade.

On your behalf, we will submit a software requirement for future versions to have this ability.

Thank you!

Yeah I guess you did, sorry I just assumed you must have read it wrong.

I guess I learned something new, although I can't imagine for the life of me why anyone would ever want to do that.

Richard,

I just tested it again after reading your post. I created a program in 6.4.14, saved it. Opened up 6.2.24 and tried to open it. No luck. It tells you it was created in a newer version and can not open.

If I remember correctly, the ability to load a newer plan in an older version was identified as a (resolved) bug in the release notes some time ago. I guess they somehow messed up the version check by accident and didn't test afterwards, so it went unnoticed for some time.

Why would anyone want to do that? Well, imagine all your measurement plans are stored on a network drive and you test the newest Calypso release with one of them (of course without making a backup copy first 🤠 ), and then you click the save button AND confirm the safety prompt, because you already forgot you are using the new release. THEN you'll want to load it again in an older version 🤣 🤣

Bruce, as stated above it is possible to do if you have the previous version installed on the same computer. Previously you had to remove a previous Calypso installation before you can install the new version. That restriction has been removed. So it is now possible to have multiple installations however Zeiss does not recommend it. I have several customers that will not upgrade so I can write the program in one version and open it in the version they have and re-save it in their version. It works well and is great to have that option.

I had a similar issue. A new supplier created some programs in Calypso version 6.8, but I have 6.6. I could not open their programs, but I needed to review them. I ended up having to install the latest service pack,(6.6.28) and then the patch (6.6.2811). Then I was able to go into the program file, open the version file using note pad, change the version to 6.6.2811, and then overwrite the file. I was able to open the programs without issue after that. In the past, with different versions, I have been able to simply change the version in the version file.
