Any impact of upgrade db2 from V10.5 to V11.5? Good day,

Due to the DB2 v10.5 will end of support on next year April. I would like to change my application database version to v11.5. 

Before apply this to production, I do it in my local VM first. The following are the steps I have done:


backup original database.
Install DB2 v11.5, because its same environment, do I cant have same user call db2inst1, so I create another instance call db2inst2.
log in as db2inst2, run restore command to restore the image file I done in step 1 :

db2 restore database mydb from /home/db2inst2 on /home/db2inst2


After this, I configure my Jboss server to point to this new database, application can log in and working fine.

I am thinking that, is there anything I need to take care? or anything I need to avoid ? I am worry that there are something issue unforeseen will happen.
If you will need a Solaris Client, you won't get a client for the last version. IBM drop the support for Db2 in that platform.

Remember to rebind packages.

Also, update Db2 clients and JDBC clients to have everything in the same version.
