Plan Upgrade ACS 7.2 to 26.1 via Helm Chart

Hello,

A major migration of a customer's ACS Enterprise is planned from version 7.2.2 to 26.1.0.
Its 7.2.2 is currently under kubernets (therefore deployed via Helm chart).
I want to make sure I haven't forgotten anything in the migration stages on my plan.

In the critical points that I noted:
- migration jump from 7.2.2 to 7.4.2 then 26.1.0
- migration of the postgreSQL database from version 13 to 16
- abandonment of ASS for ASE (Solr for elasticsearch)

So my migration plan would be:
PROD 7.2
↓
Clone infra
↓
ACS 7.4.2 + PG13 + Solr
↓
DB Migration
↓
Validation
↓
Dump PostgreSQL 13
↓
New environnement
↓
ACS 26.1 + PG16 + ASE
↓
DB Restore
↓
Full reindex
↓
Full Validation

with, in this plan, the contentstore in RO for the migration jump in 7.4.2.

Does this seem coherent to you?
are there any elements that I would not have taken into account?
Thank you for your feedback.

Sincerely.
