Ver 15.X and restriction for schema=public

[Bharani SV-forum]

 TeamI am in the process of upgrading EC2-PGS ver 13.X to 15.X I am aware  
since ver 14.X, we have restriction in the usage of schema=public and the DBA 
need to grant exclusive priv for the tagged db user's.
Assume i want to enforce it,Can i retag all the object 
tables/indexex/packages/procedures/functions etc tagged under schema =public to 
a newly created schema e.g = schemaname = allowallusr and grant respective 
priv's.
Whether it will resolve the issue, as application time need time to validated 
all the use case for testing the objects which is present under schema=public 
and ported to new schema= allowallusr .
Any suggestions or best practise
