How to solve invalid objects when i "transporte a Database Using an Export Dump File"?

Hello everyone, I have a problem to be solved, please help。

i transporte a Database Using an Export Dump File，the impdp command is:

expdp system/oracle1234 full=y transportable=always version=12.0 directory=expdp_dir dumpfile=full.dmp logfile=full.log

（source db version：11.2.0.4 dest db version：19.13）

I find there are some invliad obejcts in the dest database：

select owner, count(*) from dba_objects where status = 'INVALID' group by owner;

How to fixup these invalid objects？

Thanks very much。
