Is it safe to add LVM cache device to existing LVM volume group while filesystem is mounted?

I have an existing LVM volume group with a 10 TB logical volume mounted as an ext4 system which is actively in use. **Is it safe to run the command lvconvert --type cache --cachepool storage/lvmcache-data storage/data while ext4 filesystem is already mounted on storage/data?** (The storage/lvmcache-data has been previously configured with lvconvert --type cache-pool --cachemode writeback --poolmetadata storage/lvmcache-metadata storage/lvmcache-data in case it makes a difference.) I would assume yes, it's safe to add cache on-the-fly to online volume with mounted filesystem, but I couldn't find documentation either way.
