oracle upgrade fails with ORA-01691: unable to extend lob segment SYS.SYS_LOB0000007354C00004$$ by 1

We are doing update from oracle 12.2.0.1 to 19c, during update got error

ORA-01691: unable to extend lob segment SYS.SYS_LOB0000007354C00004$$ by 128

in tablespace SYSAUX

ORA-06512: at "SYS.PRVT_EMX", line 367

ORA-06512: at "SYS.P

RVT_EMX", line 349

ORA-06512: at "SYS.PRVT_EMX", line 763

ORA-06512: at line 1

I have read in some other posts, people have suggested to increase the table space size and then continue.

The question I have is, as we are migrating the existing table details to new database , my upgrade should not end up with this failure as this was the setting which was working in 12.2.0.1 with the configuration.
