How to Upgrade and DB doctor for all 1500 parts of PCB footprints from 16.2 to 17.2

The uprev command has the -b option which allows multiple files and/or directories

The documentation explains the various options...

Hi David, thanks for immediate response,

Could you please explain more about procedure like where I can find the "uprev" option or do I need to enter on "command window"

I ran command D:\Raam\Raam_LIB\Allegro> allegro_uprev -b. it did not worked

then I found the "allegro_uprev.exe" at C:\Cadence\SPB_17.2\tools\bin and copied it to my library D:\Raam\Raam_LIB\Allegro. then ran the exe file from library folder. still did not worked

then I entered command to run D:\Raam\Raam_LIB\Allegro\allegro_uprev.exe still not working.

Go to  D:\Raam\Raam_LIB\Allegro> and run allegro_uprev.exe -b and that should do it. 

Make sure to run the commands listed in here:

Could you clarify please. I only have a C: drive on my computer, as well I attempted to locate Raam and it does not exist on my device.

That's because D:\Raam\Raam_LIB\Allegro is where the original poster ( Raamvishnuraja )  had his library folder located...

You library folder is wherever you configured yours to be...

So in allegro, in the command window. I would have to be in the folder where my footprint library is. Then run:

allegro_uprev -b

No, not in Allegro, since you are using Windows in a 'command prompt' window
