When testing an upgrade of a customized RHEL6 to RHEL7, sometimes we see that upgrade fails with a ton of messaged like this:

  building RPM transaction, one moment...
  error: db5 error(-30969) from dbenv->open: BDB0091 DB_VERSION_MISMATCH: Database environment version mismatch
  error: cannot open Packages index using db5 -  (-30969)
  error: cannot open Packages database in /sysroot/var/lib/rpm
  Warning: failed to add <some_pkg_name> to the transaction
  Warning: couldn't add <some_pkg_name> to the transaction

Can't say for sure which change in the system causes this bug; sometime upgrade works fine, sometimes it fails in almost the same configuration.

There are some reports in the net concerning this issue that recommend to remove __db* indexes in such situations (e.g., https://bugzilla.redhat.com/show_bug.cgi?id=916408#c6).

And indeed, forcing removal of these indexes in do-upgrade.sh seem to completely eliminate the problem in our cases.
