Thanks Neil for your reply,



Thanks to all who take the time to reply to the following.



I have a follow up question that goes along with this subject and of course anyone can chime in.



The new Windows 2012 R2 64 bit server will have the 64 bit Firebird server v2.5.4 install on it (But alternately may have Firebird 32 bit server installed instead based on the answers given below).



All client work stations are Windows 7 64 bit and currently have the Firebird 1.5.3 32 bit fbclient.dll installed on them and they all currently use the Windows 2003 32 bit server with Firebird 1.5.3 Server running on it. The application written in Delphi XE5 that connects to the Firebird server is currently a 32 bit application. Will be a ways down the road before releasing a 64 bit version of the application.



So questions:

1) Since the application is a 32 bit application, should I install the 32 bit version of the Firebird server or is it OK to install the 64 bit Firebird server on the Windows 2012 R2 64 bit server?

2) If I should be installing the 32 bit version of Firebird Server on the Windows 2012 R2 64 bit server, then I would assume I would uninstall the current 1.5.3 32 bit Firebird Client and install the new 2.5.4 32 bit Firebird client, right?

Bottom line is:

If I was to install a 64 bit Firebird client on the Windows 7 workstations, would it work with either a 32 bit or 64 bit firebird server on the Windows 2012 R2 server?

And would the 64 bit Firebird client on the Windows 7 workstations, work with the 32 bit 1v.5.3 firebird server on the old Windows 2003 32 server?



I guess all can tell I’m a little confused on if 32 bit and 64 bit Firebird server/client can be mixed and matched for v2.5.4 and if whatever is placed onto the work stations would be able to connect to v1.5.3 Firebird server running on the old windows 2003 32 bit server.



Any help is really appreciated and of course if I need to clarify please ask.



Mike

Hi Mike,



I don’t have direct experience of using FB Client v2.5 to access v1.5 databases but my understanding is that it should work okay for you. We certainly access v2.1 databases with the v2.5 client okay and accessed v1.5 databases with the v2.1 client without issue.



From what I have read and experienced the clients are backwards compatible but you have to be careful accessing a newer database with an older client which doesn’t usually end well.



I believe you would need to uninstall the v1.5 client first, then reinstall the v2.5 one.



Cheers,

Greetings All,

We are installing a new Windows 2012 R2 64 bit server at the office and eventually will restore a Firebird 1.5.3 Database to 2.5.4

On one windows 7 64 bit client I will install the 2.5.4 firebird client.

A few questions:

1) Do I need to uninstall the 1.5.3 client first?

2) After the 2.5.4 client is install and I’m able to access the new 2012 server successfully, can this same firebird client be used to connect to the old firebird 1.5.3 database on the 2003 windows server?

Thanks,

Mike
