have written many applications and get requirement of upgradation to new
version CRM 4.0, from bigning of this year, it was painful activity I was
performing. Microsoft CRM Team should work for such things while new version
release as it will be problamatic for every one and every time in future
versions. Anyhow there are few things keep in mind while doing your upgradation
of custom applications.
I have done upgradation of following things and done successfuly with passage of
time.
1. Callouts / Pluggins (mostly work , but some time need to modify the dlls and
Code
2. Reports (Custom reports need to modify most of the cases)
3. Javascript ( Normall Javascript code related to customization works fine ,
but some time like filters lookups, accessing CRM webservices in Javascript
need to modify with new code. For more see CRM SDK or my upcoming posts related
to Javascripts upgradation etc.
4. ASP.Net Application, As I have written many ASP.Net applications for
customers , need to modify the code.
a. Remove your web reference and then add new one
Server Path/MSCRMServices/2007/CRMService.asmx b. Your code should be migrated
to VS 2005 / .Net 2.0
c. Check CRM new data types like double , CRM Money etc
5. Restart Async Service if you are attempt to do IIS restart (iisreset). Above
Points need to check regarding upgradation of your code.
6. .Net Assemblies for CRM Workflow. Also check your custom applications link
to workflow (Workflow .net assemblies), some time you have to recompile and
link that.
