First is important to note that the main clauses of ISO 27001:2013 (i.e., clauses 4 to 10) are still valid. The 2013 version of the standard was confirmed in 2019, and the new version of the standard, expected to be published still in this year, will have modifications only related to Annex A.
Although the total number of controls had been reduced from 114 to 93, none of the old controls have been excluded (most of them have been merged), and you only have 11 new controls.
Considering that, in case you are currently compliant with ISO 27001:2013, your main effort will be on reviewing risks and legal requirements to check if these new controls need to be considered in your implementation.
The effort to transition to the 2022 revision is probably 10 to 20% of the time you needed to initially implement ISO 27001; alternatively, this effort can be cca 5% if you are using a tool like Conformio.
