Hi Abhijith;
Since you have multiple object errors in the screen capture you posted, I would proceed as follows:
1) Run the Migration Assistant utility in PB 12.5.x on your PB 9 source code and see if there are issues located in that release that need to be fixed before you migrate. If the MA points out issues - then fix them in PB 9 and redo the migration.
2) Have you tried performing a FULL BUILD from the current target?
BTW:
a) Are you using PB Classic or PB.Net?
b) What version and build of PB are you using exactly?
c) Is this a PFC based application?
FYI: PB 12.5.x is Unicode and PB 9 is ANSI based. You may have to look at this aspect as well depending on the features you chose.
HTH
