docs(release-notes): make the 0.6.2 to 1.0.1 upgrade guide runnable e… - #2312

Conversation
…nd to end The upgrade guide described the migration stops but left operators to work out the commands. This adds the executable procedure: bounded Cassandra migration Jobs, the two-rotation OpenBao sequence, the ICMS and NVCT bridge helpers with their backfill records, the finishing syncs, backups, and the compute-plane re-registration checks. A live rehearsal (0.6.1 to 0.6.2 to 1.0.1, three Cassandra and three OpenBao members, real GPUs) ran every command as written and found these corrections: - The NVCT health backfill gate required withoutLegacyHealth=0. That count covers completed and canceled tasks, which never had a legacy health value, so it is normally nonzero. Gate on missing, mismatched, failed, and current + withoutLegacyHealth = scanned instead. - function invoke and task commands need keys from nvcf-cli api-key generate; the administrator token alone returns 403 and 401. - The bounded Job needs imagePullSecrets for authenticated registries, and REPLICA_COUNT must be re-read and checked before the first Job because the event_ledger migration bakes it into the keyspace definition. - kubectl 1.31 or later is required for kubectl wait --for=create, and the procedure depends on shell state carried between steps. - Helm can time out on a long Cassandra roll while the StatefulSet continues; rollout status is the gate. Relates to #2191 Signed-off-by: Manasi <mmahadik@nvidia.com>

…grading The 1.0.1 stack does not forward cassandra.persistence.subPath to the Cassandra chart, so installations that adopted Bitnami volumes in 0.6.1 render a StatefulSet without the subPath and would start empty members. The volume claim template check does not catch this because the subPath is part of the pod template. Add a data volume mount comparison next to the volume claim template check, a stop condition, the secrets-file override that carries the setting through every Cassandra sync including make install, and a pointer to the optional relocation script.

Three checks could pass when the operator should stop: the rendered subPath grep matched any mount, the REPLICA_COUNT guard only tested for a non-empty value, and the final migration log check printed matches without counting them. Anchor the render check to the data mount, record the replica count at backup time and compare against it before the first Job, and require exactly seven no-change lines. Define BACKUP_DIR before its first use. Signed-off-by: Manasi <mmahadik@nvidia.com>

TL;DR
The 0.6.2 to 1.0.1 upgrade guide describes the migration stops but leaves the
bounded Cassandra migrations, OpenBao rotation, bridge rollouts, and backups as prose. Add the commands for each step and correct the gates and prerequisites that an end-to-end run showed to be wrong.
Additional Details
