Double check your initial parameters Select Name,value from V$parameter where isdeprecated=‘TRUE’
Scenario Cursor_sharing = EXACT | Force (12c)
Cursor_sharing = SIMILAR | Exact | Force (11g)
This parameter is not deprecated , but the value SIMILAR is not available in 12c . Review all the parameters you use in the spfile/ init file does not matter id is deprecated or not.
Inside Database Parameters
Don’t change immediately COMPATIBLE
Review the know issues on each platform/version/vendor suggestion
Source must be Metalink not google.

ways verify the effect in your environment
Inside Database Parameters
AIX _use_single_log_writer=TRUE
12.1.0.2 Don’t’ use Memory_target < 1G instead use sga_target and pga_aggregate_target
People Soft _optimizer_aggr_groupby_elim= FALSE
Inside Database Patches
11g SQL>@catbundle.sql psu apply SQL> !$ORACLE_HOME/OPatch/opatch lsinventory -bugs_fixed | egrep -i 'DATABASE PSU|DATABASE PATCH SET UPDATE‘
12c $ORACLE_HOME/Opatch/datapach –verbose SQL> select patch_id, patch_uid, version, status, description from dba_registry_sqlpatch where bundle_series = 'PSU';

PAYYING ATTENTION ?
The name of these bundle patches was changed to "Database Proactive Bundle Patch" in April 2016.
Each bundle patch includes the following component patches in separate subdirectories:
• Clusterware component the same as GI PSU
• ACFS component the same as GI PSU
A database bundle component that includes all DB PSU fixes along with additional fixes specifically for Engineered Systems and DB In-Memory
Inside Database Patches
SQL>select patch_id, patch_uid, version, status, bundle_series, description
from dba_registry_sqlpatch;
Bundle_series column can has the values [ PSU | DBBP ]
Check all the pluggable database has all the patches.
SQL> alter pulggable database all open;
SQL> SELECT s.con_id, s.patch_id, s.patch_uid, s.description FROM cdb_registry_sqlpatch s order by 1,2;
if not all pluggable databases are sync , what can I do ?
./datapatch -verbose -pdbs MY_PLUGDB12C

simplifies viewing of past performance and diagnosis of issues.
The -MGMTDB has now become a single-tenant deployment having a CDB with one PDB
Average growth size per day per node is roughly 650-750 MB. E.g. a 4 node cluster would lead at the default retention of 3 days to an approximate size of 5.9-6.8 GB
