Hi All,

Came across a versioning issue with rpm.rte when performing an AIX 7.1 to AIX 7.2 migration. The version of AIX pre-migration was 7100-05-02-1810, and the version of AIX post-migration is 7200-02-02-1810.

The problem is, that if the version of rpm.rte is the same before and after migration, during the migration, AIX doesn't update the package, as it's already installed (and at the same version). In turn, the AIX-rpm virtual package version isn't updated, which causes some dependency issues (especially with libgcc). You can resolve this by running /usr/sbin/updtvpkg.

This is more of an FYI if anyone else runs into this issue.

Before migration

# oslevel -s
7100-05-02-1810
# lslpp -l | grep -i rpm.rte
  rpm.rte                   4.13.0.2  COMMITTED  RPM Package Manager
  rpm.rte                   4.13.0.2  COMMITTED  RPM Package Manager
# rpm -qa | grep -i AIX
AIX-rpm-7.1.5.15-1.ppc

During migration

# grep rpm.rte lpar_alt_mig.log
rpm.rte                   4.13.0.2        Already installed

After migration

# oslevel -s
7200-02-02-1810
# lslpp -l | grep -i rpm.rte
  rpm.rte                   4.13.0.2  COMMITTED  RPM Package Manager
  rpm.rte                   4.13.0.2  COMMITTED  RPM Package Manager
# rpm -qa | grep -i AIX
AIX-rpm-7.1.5.15-1.ppc

Issue upgrading libgcc

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Fixed by updating the AIX-rpm virtual package verion

# /usr/sbin/updtvpkg
Please wait...
# rpm -qa | grep -i AIX
AIX-rpm-7.2.2.15-2.ppc
# yum upgrade libgcc
