i have installed FlexBuilder 3 and i have developed an application with flex SDK 3 .
Now i want to turn into Flex4 becoz of new features.
then How to migrate Flex 3 Application into Flex 4.
becoz flex builders 3 compiles mxml files and run in Flash Player 9 but flex 4 requires Flash Player 10.
is there any problem if i change SDK 3.2 to SDK 4 in my flex builder 3.
Can any one help me regarding this?.
Thanks in advance
Flex 3 code will work in Flex 4 too.. just import that project into Flex 4 that will work.. Flex 4 will support both spark and mx name spaces.. So its not a BIG problem... Hope this will HELP you..
