Create DB2 instance with 2 DB2 server versions installed

I have DB2 v10 and v11 server installed (LUW). I created a DB2 v10 instance and migrated it to v11. Now when I want to create a v10 instance, it always creates v11 instances. How can I create an instance in v10?

/opt/ibm/db2/V10.5.11/instance/db2icrt -i instf instname

is what I use to create it 

/opt/ibm/db2/V10.5.11/instance/db2icrt: symbol lookup error: /opt/ibm/db2/V10.5.11/instance/db2icrt: undefined symbol: _ZN15UtilityObserverD1Ev

is the message I get. No matter if I reuse the same name of the instance I migrated and deleted after that or a new name. And the instance is created as v11.

I have a root installation and the db2icrt is done as root.

The question had two symptoms. The first syptom "symbol lookup error" was corrected by ensuring that the shell had no references (apart from in $PWD) to any Db2 product or installation.

The second symptom, db2icrt appeared to be creating the wrong version instance was corrected by adjusting the startup profile for the new instance-owner.

The solution was to ensure that the newly created Db2-instance dotted in the correct db2profile in the shell startup file(s) for the new instance-owner.

So for example, if the Db2 v10.5 instance-owner is db2inst8, its startup profile should dot in the /home/db2inst8/sqllib/db2profile , and meanwhile if the Db2 v11.5 db2instance is db2inst1 then its startup profile should dot in /home/db2inst1/db2profile.
