Hi Shirish
You can try below steps
=================
The general recommendation is to eliminate such inconsistencies (TADB6, IADB6, tbsp names, database partition group names) before starting an upgrade.
If you want to continue with the current upgrade:
Identify the tablespace created in the wrong database partition group, most likely the one named after the target upgrade as older tablespaces are more likely to contain data from an old upgrade.
Execute the following command to show which data partition group the tablespaces were created in.
db2 "select tbspace, ngname from syscat.tablespaces"
Check that there are no objects in this tablespace using the following command:
db2 "with total_objects (total_objects) as ( select count(*) from syscat.tables where tbspaceid in (<TABLESPACE_ID1>, <TABLESPACE_ID2>) union all select count(*) from syscat.indexes where tbspaceid in (<TABLESPACE_ID1>, <TABLESPACE_ID2>))
select sum(total_objects) from total_objects";
Here, <TABLESPACE_ID1> is the ID of the data tablespace, and <TABLESPACE_ID2> is the ID of the index tablespace.
The TABLESPACE_ID can be obtained from an output of the following command:
db2 list tablespaces
If there are no objects created in the tablespace, drop the wrongly created tablespaces. Recreate the tablespaces:
Use parameter IN NODEGROUP <Database Partition Group name> with the CREATE TABLESPACE statement.
Refer to the IBM Knowledge Center for more details.
Please make sure all the table spaces specified in the CREATE TABLE statement belong to the same database partition group.
If "IN NODEGROUP" is not specified, "IBMDEFAULTGROUP" is taken as the default database partition group.
Since no table can be created in the data+index-tbsp-combination due to SQL1754 the tablespace in the incorrect database partition group can be dropped and recreated using the same database partition group as the other tablespaces. Continue with SUM by starting phase DBCLONE from the beginning (INIT)! DO NOT continue from the point where it stopped (REPEAT).
============
Hope it helps
