Hello All,
I am trying to do an inhouse lab upgrade to vcenter appliance 6. I first upgraded from vcenter 5.5 windows to Vcenter 5.5 appliance using the upgrade fling.
Next i want to do the upgrade to vcenter 6 but this fails with an database schema error message at stage 4 during it's validation.
The exact error message is:
Source vCenter Server schema validation found an issue.
Read the vcdb_req.err log file and address the issues found.
This file i found on the appliance itself and i opened it with command:
more /var/log/vmware/upgrade/vcdb_req.err
At the top of the file i see the following messages:
------------------------------------------------------------------------------------------------------------
WARNING: Cannot execute statement(rc=100).
DELETE FROM VPX_TABLE
^^^^^^^^^^
WARNING: Cannot execute statement(rc=100).
DELETE FROM VPX_INDEX_COLUMN
^^^^^^^^^^
WARNING: Cannot execute statement(rc=100).
DELETE FROM VPX_SCHEMA_HASH
^^^^^^^^^^
Error while executing ./Upgrade-v2013-to-v2015/postgresql/validate_PostgreSQL.sql:310, reason: Cannot execute statement(rc=-1).
And at the bottom:
1 [P0001](7) ERROR: ERROR ! Extra sequences: vpx_host_cnx_seq;;
Error while executing the query
------------------------------------------------------------------------------------------------------------
How can i pass or solve these error messages to do the upgrade ?
