Cluster Upgrade 8.0 > 8.2: KVStore Migration to WiredTiger

We are planning upgrade our clustered deployment from 8.0.5 to 8.2.1

In case we plan to migrate the KVStore engine to WiredTiger, do we have to mandatorily go through the v8.1 step as mentioned in https://docs.splunk.com/Documentation/Splunk/8.2.1/Admin/MigrateKVstore ? 

Per my understanding, the steps for this method stands like this

  1. Upgrade cluster from 8.0.5 to 8.1.5 
  2. Migrate the KV store after an upgrade to Splunk Enterprise 8.1 in a clustered deployment
  3. Upgrade cluster from 8.1.5 to 8.2.1

In case we decide not to use WiredTiger for now and complete the upgrade to 8.2.1, can we migrate the KV  Store to WiredTiger at a later point of time? 
To elaborate, will the following work: 

  1. Upgrade cluster from 8.0.5 to 8.2.1 
  2. At a leter time, if WiredTiger is needed, migrate the KV Store as instructed in Migrate the KV store after an upgrade to Splunk Enterprise 8.1 in a clustered deployment

We do not use KV Store at all now, apart from whatever internal functions that Splunk Enterprise uses it for (no ITSI or ES as well), but want to plan ahead in case we use it in the future. 

Thanks in advance!
