Dear Team,

We recently migrated from AIX OS version 7.2 to 7.3 during that migration perl version automatically upgraded due that my application team facings errors while running the programs and they got below error.

I am mentioning both the old and new Perl versions for your reference.kindly advise on how to resolve this issue.

perl version before 7.3 migration:

#lslpp -l|grep perl

perl.libext 2.4.5.0 COMMITTED Perl Library Extensions

perl.rte 5.28.1.7 COMMITTED Perl Version 5 Runtime

perl.libext 2.4.5.0 COMMITTED Perl Library Extensions

perl.rte 5.28.1.7 COMMITTED Perl Version 5 Runtime

perl version after 7.3 migration:

#lslpp -l |grep perl

perl.libext 7.3.3.0 COMMITTED Perl Library Extensions

perl.rte 5.38.2.1 COMMITTED Perl Version 5 Runtime

perl.libext 7.3.3.0 COMMITTED Perl Library Extensions

perl.rte 5.38.2.1 COMMITTED Perl Version 5 Runtime

Hi Vivek,

In this case custom module needs to reinstalled with latest perl.rte.
