[PCB_FORUM] Re: Has anyone been able to "backrev" from version 16.0 to version 15.7?

Before you gave up , you might one to look at this doc by Cadence.
http://www.cadence.com.tw/upload/Faq/F000091.pdf

It has to do with Down Rev from 15.xx to 14.xx. Which is not available 
inside 15.xx maybe is the same with 16.0 to 15.XX???

That's what I thought might be the case and also what I was "afraid" 
of......C'est la vie....

I would say since the first thing it does is uprev the database and they 
went to an “object oriented database” for 16.0 there is not going back, 
unless Cadence writes a downrev script.

Hi Gary,
Thanks, I see it in 15.7 to other 15.x but I am hoping that it is also in 
16.0 to 15.x? or is it a major release and there is no going back?
Thanks,
Dharma

Hey Dharma,
 
No, I think I misread your post!
 
Ok, so in 15.5.7, I can go:
 
File -> Export -> Save design to 15.0…
 
or
 
File -> Export -> Save design to 15.2…
 
Do you see this option in File -> Export? This might only work within a 
major release.
 
Good luck

Hi Gary,
 Thank you. I was actually looking to find out if once a board is in 
version 16.0 whether or not it can be opened in 15.7 and worked on by 
someone else.
sorry for the lack of clarity,
Dharma

Dharma,
 
Below is a post I saved from Michael Catrambone.
 
I think this is what you are looking for. I haven’t tried it myself, I 
still just have 15.5.1 loaded.
 
Good luck

Subject: [PCB_FORUM] Re: Switching between two versions of Allegro PCB
Importance: High
 
Hey Gary,
 
I have had great success using the Cadence Switch Release executable which 
has been part of the standard Cadence install for some time now <Install 
Dir>\tools\bin\switchversion.exe).  This will list all the Allegro 
releases at the time of installation and you simply select the release and 
click OK.
I have 15.5.1, 15.7 and 16.0 loaded on the same PC and I execute the 
Cadence Switch Release executable from the last loaded release and select 
the lower version you would like to run.
 
The only thing that I have to worry about is the location of the PCBENV 
directory for each of the releases which can be easily controlled by 
re-targeting your HOME directory to a different location.
 
New to SPB 16.0, is a new Windows environmental variable
(ALLEGRO_PCBENV) that gives the ability to re-target your PCBENV directory 
to a different location without having to change you HOME directory.
 
Hope this helps,
Michael Catrambone

Hi Everyone,
I thought I had seen somewhere that it was possible to take a board done 
in 16.0 back to 15.7 but now I am not finding any info on that...has 
anyone been able to accomplish this?
Thanks in advance,
