I attempted to perform a redirected restore of V8.2 db into a V9.5 instance and received the warning msg below. From what I have read this should be allowed. How Any ideas what the issue maybe?

SQL1277W A redirected restore operation is being performed. Table space
configuration can now be viewed and table spaces that do not use automatic
storage can have their containers reconfigured.
DB20000I The RESTORE DATABASE command completed successfully.

njs75d-0004:/home/db2inst4/RR/rr_PROD/scr> db2 connect to dbtest
SQL1119N A connection to or activation of database "DBTEST" cannot be made
because a previous restore is incomplete or still in progress. SQLSTATE=57019

Apparently, you did not complete the redirected restore procedure. Check the manual for all necessary steps.

you need to issue SET TABLESPACE CONTAINERS command for every tablespace of the DB and then RESTORE DBname CONTINUE to start doing restore

Also, note that you can only do this with an offline backup.

You can't restore an 8.2 online backup into a 9.5 database - 8.2 log files can't be read by 9.5.

You can also look into exporting and then importing data using db2move command....
