I have powerdesigner 9.5 and have reverse engineered the database. Now the problem is that i am unable to open the same file in lower version of powerdesigner 9.1 or 7. Is there any dll or utility thru wich i can open the file of higher version into a lowerversion powerdesigner.

Its urgent.

Thanks is advance

I don't know have much knowledge about powerdesigner but may be i can help u. Can u clearify about the file ? which file u r not able to reopen ?
The file is related to backend or frontend ?
Which database u r using ?

Can u just describe your problem in detail ?

I also does not have much idea abt powerdesigner..

Can you opne the file in note pad, and check if it's in text format or binary...
If in text format, try comparing it with a file in previous version..
If in binary format, is there any option to exposrt it to text format .. Like we have in PB ??

Thanks sandeep_patel, Vikas_Dixit for your comments.
The problem is very clear and simple but very urgent. ;-)

I have got a powerdesigner file which has been made using sybase Powerdesigner 9.5 version. This file cannot be opened using lower version (7.0) and i donot have a lower version of power designer. Is there any way with which i can convert the file to 7.0 version or some older version. ?

it think it's not possible.
and whatever the vikas is asking for is correct...b'coz in powerbuilder we can have a file for each object that contains the version information....so whatever the file u have just check whether is there any version ?

and try to change ...but i don't think it will work..

take a chance.........^_^

Not possible to achieve what you want.
PD9 and above introduced lots of new things like workspace/ integration with pb and so on.
vice versa is possible ,  pd6.5 files and above can be opened in upper versions like in any normal applns, i guess.

Have you got only the pdms or by chance do you have the script files.
Then you could reverse-engineer uisng the script files ?

Alternatively you can download PD10 ( 15 days trial ), available from

Read the PD9 pdm in PD10
create the script files and
then reverse engineer the d/b in PD7 using script file as the source
and you have the databse ready.

Hope that makes some kind of sense ;-).

I had a similar issue with PowerBuilder.  I needed to move from V7 to V5.  I exported the files, changed the version and tried to re-import.  After making other small changes (V5 did not have html dws) it re-inported ok.  Hopefully the files are in some sort of text format that can be hacked or exported and re-imported.

The points should go to me alone.sandeep_patil feels that there is no soln to the problem
while the two ways suggested by me are proper and will work under any circumstances.
