How To fix Oracle 19c PDB clone cross differente RU CDB, Then PDB in restricted

几年前12c刚release时测试过一系列pdb的功能,其中有小测试一下12.2的pdb hot clone,最近看到一个案例是19c 在不同的RU版本的CDB之间通过PDB clone迁移的数据库,从19.6 clone到19.11后PDB 变为restricted受限模式,查询PDB_PLUG_IN_VIOLATIONS看到如下错误:
‘19.11.0.0.0 Release_Update 2104130040’ is installed in the CDB but ‘19.6.0.0.0 Release_Update 1912171550’ is installed in the PDB
