MySQL Replication to InnoDB Cluster

Hello,
We have a few MySQL databases running in 5.x. For example, we have (2) instances running 5.5 version, and (1) instance running 5.1 version. Those instances are either running in MyISAM or InnoDB storage engine, but not in type of any MySQL cluster environment. The binlog_format is all set to mixed.
I created a freshly new MySQL InnoDB cluster. We need to replicate the existing database instances into the cluster. My thought is to create MySQL either A-B replication topology, or A-B-C replication topology. For example, for version 5.5, the database instance replicate to the cluster running 8.0.22 version; for version 5.1, the database instance replicate to a intermediate instance of 5.5 version, then replicate to the cluster running 8.0.22. The cluster database instance has binlog_format set to rows.
Are those replication possible to do?
Is there any Oracle document detail for replicating a MySQL instance to InnoDB cluster?
Thanks,
-Xinhuan

First of all MySQL 5.1 and 5.5 are very old, not supported, and a lot has changed since they were mainstream. MyISAM is not recommended for litany of reasons that I will skip here. Replication for your older versions to anything newer is going to be problematic at best. 5.7 can replicate to 8.0 but I would not waste time on trying 5.1 or 5.5 to 8.0.
I suggest using mysqldump (or similar) and load the 8.0 cluster with the older data. I would recommend the new mysqlsh dump utilities but they are not compatible with those older versions of yours.
And I do recommend reading https://dev.mysql.com/doc/mysql-shell/8.0/en/mysql-innodb-cluster.html

Th Clone plugin could be used for replication.
