Agreed. Even then, it's no golden guarantee, you still may have to change the component to get it to compile (and it might require considerable work), but you're improving your odds considerably this way. Sometimes you get lucky and others have gone through the modifications already and you can find the changes on the Internet.

Two other factors I take into account are: How likely is it that the components will be around in a few years' time, and can I design the code around it or encapsulate the interface to the component so that it will be easier to switch the component for another.

Thanks for the link, Loïs!
Jason, I plan to keep a work log on this blog, keeping track of how I progress and where I stumble (or fall flat on my face), as well as questions that arise and their solutions.

2008-11-19T17:08:12.441+01:00

We migrated a 1.5+ million line codebase from D5 to D2006. We split it up in several steps: (1) upgrading or replacing all third party components that weren't compatible with D2006, (2) porting or replacing all in-house components to make them compatible with D2006, and (3) porting the source code itself.

I could be looking to convert from D6 to D2009 in the not so distant future so I'd be interested in how this goes for you. Any chance you could put some posts together telling us your pitfalls and successes?

2008-11-19T08:33:53.009+01:00

Thank you for your feedback, guys! One part that is particularily worrisome is the designtime components. There was a fundamental change in approach between D5 and D6 if I remember correctly, splitting design code and use code more rigorously?

Anyone know of articles that share knowledge on the particular aspect of design time component migration?

Fortunately, all my third party libs are (or will shortly be) available for D2009.

2008-11-19T07:16:10.682+01:00

Definitely skip 2007 - otherwise you would need to convert some parts twice - especially if there are 3rd party components. Also, it may be easier to rewrite some parts of the code instead of fixing everything, and the new generics (e.g. TList<>) may come in very handy when doing that. You need D2009 for those.

Instead of spending time on D2007, I suggest that you spend time on refactoring your app inside Delphi 5, so that you can compile it in smaller parts. When you have made a sub-project that only compiles 50,000 lines of code, it is much easier to make that compile with Delphi 2009. Unit tests are also a very, very good idea, and all this can be done inside Delphi 5.

2008-11-18T23:29:16.035+01:00

I agree with SKamradt, but if you open it in 2009 and find you are dealing with a lot of issues in addition to unicode then it might make sense to step through 2007 first so you can fix everything but Unicode first. I generally like having milestones where it is complete and working in the process.

2008-11-18T23:15:42.022+01:00

If you have all of the 3rd party components in Delphi 2009, then I would skip 2007. The largest piece to overcome would be the string to unicode, but I have yet to have a serious problem with any of the code that I have migrated.

Problem solved. Broken load balancer, it seems.

2008-10-02T23:56:09.804+02:00

If you remember that after Deplhi 7, Borland produced a .NET version and now we are back to native applications. Says it all really.

The browser apps give options which were not there 15 years ago, so I respect that I may need to develop a browser app for some situations and native code for others. I would determine which one to develop with in the same way I would choose a language to use for the project at hand.

There are 10s of 1000s of Delphi programmers out there and some of us are around from before Delphi 1. I am still using it and if they are concentrating on native code then that sends a shot across my bow.

In conclusion, horses for courses - but the default is native code!

Lars,

Infomercial or not he makes good points. Native code will always perform better.

It is good to be a Delphi developer ;)

Cheers,

2008-09-24T09:08:57.424+02:00

Thanks, Alec! Useful info! I assume the Daylight Saving Time factor can be tricky as the dates have changed over the years.
I guess a more reliable approach would be to calculate and add the time offset yourself. For my use, the the dates don't go very far back and the software runs in a controlled environment (with regards to Windows updates/patches) - so it is less of a problem for me.

2008-09-24T08:52:23.867+02:00

@nf4l: Are you trying to access the new forums (embarcadero) or the old ones (borland)?
The new forums are a bit faster now, and although I am not 100% certain, it seems the slowdown was/is related to https (ie SSL). YMMV.

2008-09-23T02:57:00.000+02:00

FYI: SystemTimeToTzSpecificLocalTime function cannot be used to convert historical datetime in common case in XP and 2000 (I am not sure about Vista). Microsoft guys say only current datatime converted correctly and even those ones not always (it depends on some windows updates). We had a big trouble there and wrote special convertion function that uses real historical data :).

@Craig: I hope you are correct with regards to D/L traffic. I also hope they whip that forum back-end into shape real soon, as the forums are next to unusable these days. Not good when you have a new version and loads of interest.

2008-09-16T20:51:29.722+02:00

I'm close to certain that your speculation is incorrect. Most of the downloads go through Akamai, not CodeGear. The issue with the forms this morning is the same issue I've seen in previous weeks. I'm pretty certain it's a problem with the forums back end, not cross traffic from other services.

2008-09-16T16:02:31.456+02:00

Well, you could see it the other way around as well. Traffic shaping would also ensure that the forum traffic don't eat all the download bandwidth... I guess it would be even better if the download traffic and forum traffic didn't share pipes at all.

2008-09-16T15:36:46.646+02:00

"May I be so bold to suggest a traffic shaper that can throttle the downloads and prevent eating the entire forum bandwidth?"

You're joking right? People are already screaming blue murder about SA customers being last in line, now you want to throtle their downloads when the product is finally available...? If anything, I would assume CodeGear are deliberately throtling the forums (though if so, I guess a notice on the webpage reporting the fact would have been sensible).
