Altering and moving a table side effects or issues in GG 19c

Hi,

Oracle database 19.24

Goldengate Integrated architecture - 19c

I would like to know the side effects or issues in altering and moving a table(alter table move) in GG only in target side where it's being replicated not source.

I want to change inittrans & pct_free of the table and move it to and rebuild indexes.(Replicat process configured in target and this table is involved)

Shall i just simply stop replicat and complete activity in target database and start it ?

Will it cause any issues in golden gate replication ?

Note:- We are not touching anything on primary(source).
