All,

I am a Delphi developer working in an windows form application developed using Delphi 6. 
Now, we are planning to upgrade the development tool.
Can anyone provide me information related to major roadblocks that we can face while migrating from Delphi 6 to Delphi XE 3?
Should we migrate to Delphi XE 3 or any other preferred version of Delphi based on the fact that our target users will be using Windows 7 or Windows 8?
Do we have any tools or utilities to migrate the source code from Delphi 6 to higher version of Delphi?

Also, any suggestions related to best practices are welcome.

Regards,
Abhineet

(look at Ken's comment..)

search Google for : Migrate XE site:https://forums.embarcadero.com/

I always think, first look at your 3th party components and see if you can get the XE/XE3 versions for it..

greets.

Hi Abhineet,

I believe the biggest change from upgrade point of view, happened in 
Delphi 2009, when the string type has become UnicodeString. If you come 
accross lots of Unicode related problems you could try upgrading to 
D2007 first. If your application is going to be in Windows 7, you should 
upgrade to at least D2010, for Windows 8 you should go for XE3.

Usually there's a problem with reporting tools - which one do you use?

Also, if you're using BDE, perhaps you shoud consider dbExpress instead.

Regards

If your purpose is to target those OSs, Delphi 6 executables works very well on Windows 7 and Windows 8 in desktop mode.

Even the IDE works well, if you do not install it in C:/program files(x86) but in another directory, e.g. c:/progs

Hello,

if your application uses the BDE I'd recommend to upgrate to D2007 first
(with your XE3 licence you get all the older licences within a limited
period of time after purchase for free), because that's the last non
Unicode version.

There you can do the following things:

1. get familiar with the changes in the IDE, esp. rename refactoring is
   nice and helpful, XMLDOC is also helpful but still broken at a few
   places.

   About XMLDOC: just put something like that befor your method
   declarations:
   {code}
   <summary>
     My method description, what I always wanted to say about that
     method
   </summary>
   {code}

   Now when you hover over and playe you used the method the
   description will pop up.

2. Convert from BDE to dbExpress. D2007 already has the current
   dbExpress 4 architecture so you can swith while your application is
   still non unicode so you only change one thing at a time.

After that (and you made sure your program still works) switch to a
newer Delphi version and do the unicode conversion. You already got some
links which should contain some usefull documents about what to consider.

Greetings

Hi Kris,

I am using Quick Report as the the reporting tool.

Hi Abhinet,

As you probably know Quick Report is no longer part of Delphi. I think 
you should still be able to buy though. Alternatively, you might 
consider rewriting your reports in Fast Reports (not sure what other 
options are available for reporting in XE3).

I believe you should look into the issue of reporting first.

I recently went through the same exercise for a Delphi 4 applicaton.
Here's some links I found useful:
