[DUG] Delphi 10.2 Tokyo ready for production?

[Bevan Edwards]

Hi Jan,

I have had that headache of upgrading components from one RAD Studio 
version to the next for some time now, which is why I'm always hesitant 
to move projects to the latest version (although I am now on the 
subscription model, so I download the updates and new versions as they 
become available).

I mostly develop in C++Builder, but I think that the experience is the 
same as with Delphi.

Migrating from XE3 to XE8 was a bit of a nightmare, but I eventually 
completed that migration.  I started on the migration from XE8 to RX 
Seattle (I had to lookup the name to remind myself), but that was also a 
bit of a mission, so I never completed it.

With 10.1 Berlin I found the migration much easier, but perhaps it was 
because I had done part of the work in Seattle and also because I had a 
bit more time to sort things out.  But then moving to 10.2 Tokyo was a 
Breeze (essentially everything I had done for Berlin more or less just 
worked in Tokyo).

Going from XE5 to Tokyo is probably going to be a similar mountain of 
work as what I experienced going from XE3 to XE8, but I think it's well 
worth it.

I now use Tokyo as my main development platform and have streamlined the 
process of migrating old projects (replacing components which have not 
been maintained or upgraded with the new versions).

I believe the annual subscription model is a necessity from XE8 onwards 
(unless you want to pay full price at each upgrade), but if you're using 
it on a regular basis then it's worth the investment.

In your situation, the question is whether it's worth the investment for 
an occasional in-house developed project.  The answer is probably not, 
unless there is (a) some benefit in the target platforms offered (over 
and above what is available in XE5), and (b) you will have the time to 
put into overcoming the learning curve to use those new target platforms 
(assuming it's different from what you've been doing).


As far as I'm aware there is no Linux platform support in Tokyo, but it 
is on their roadmap.
I have played around with mobile applications in both Berlin and Tokyo, 
but I haven't produced anything for use outside of my development 
environment yet (too few hours in the day/week/month).
I have also not deployed any apps on MacOS yet (haven't needed to and 
haven't had a Mac machine available, until recently).


I hope that helps - feel free to ask any further questions.

Regards,

Bevan
