I wasn't a part of this procedure so I cannot answer anything related to that. I can, however, respond to questions for which we make information available online.
If you want specific information about the procedure I suggest you ask your registrar or you can contact SWITCH at registry@nic.ch.

Would be interesting to see a chart similar to this one: https://www.nic.ch/de/statistics/dnssec/ which shows the different algorithms in use.
You can find the DNSSEC algorithm break down for the end of 2022 for .ch on slide 21:
https://www.nic.ch/export/shared/.content/files/SWITCH_Report_Registry_2022....
DNSSEC algorithm Number Percentage 5 – RSASHA1 45 0.00% 7 – RSASHA1-NSEC3-SHA1 607 0.05% 8 – RSASHA256 97,098 8.96% 10 – RSASHA512 67 0.01% 13 – ECDSAP256SHA256 1,018,855 91.22% 14 – ECDSAP384SHA384 139 0.01% 15 – ED25519 61 0.01% 16 – ED448 14 0.00%

Since end of January 2023 you could not use them anymore.
Probably valid for new DNSSEC activations, had no effect on pre-existing algo 5/7 domains.
Same PDF has some information on slide 15 which basically states:
* Nov 2022, you can not introduce algo 5 or 7 for a previously unsigned domain * Jan 2023, you can not roll your algo 5 or 7 unless to a more modern algorithm
