<div>Dear Wallace,</div>
<div> </div>
<div>The incompatability issues can be significant especially on components.</div>
<div> </div>
<div>Many component writers do not even exist in the field anymore to update thier code to new D versions.</div>
<div> </div>
<div>For one project alone I have maintained a legacy machine runnig Delphi 4</div>
<div> </div>
<div>The "time cost" of trying to transition this to D.new is just too great to warrant it.</div>
<div> </div>
<div>Haven't noticed different exes at different times of day yet - infact seems surprisingly stable and reliable against other remarks here.<br></div>
<div>If it is not broken don't try and break it!</div>
<div> </div>
<div>If you really need new language or compiler features then if you buy new, then I suggest that you look at installing your new D in a VirtualBox to keep everything cleanly seperate.</div>
<div> </div>
<div>This also means that if you change machines you can move you virtual box to your new machine without the infernal reinstallation and migration of code/component issues of D.</div>
<div> </div>
<div><strong><u>Make sure the version of D you buy into is really stable, we bought into D.2005P and got stranded.</u></strong></div>
<div> </div>
<div><u><strong>After many months of at first promising emails CodeGear International would not even offer us a fair upgrade price to get us out of the signnificant really bad remanent bugs that they would not fix in D2005.</strong></u></div>
<div> </div>

get different EXEs just by compiling at different times of the day!<br><br>My advise then would be for you to upgrade, even if it is just to get a more<br>stable version of Delphi!<br><br>Saying that, you will not be able to use your D4 components unless you have<br>
the source. Even so, part of the VCL have changed and they may need some<br>work to get going.<br>

Professional Upgrade both the same price.<br><br>Is it worth the upgrade.<br><br>>From what I understand 2007 and 2009 makes bigger exes and are they is<br>>compatible with Ver 4 software.<br>I have quite a few third party ver 4 components installed on my system.<br>
