are due to be put into service to replace the current leased hosts. pc2* are already ready to be implemented, pc1* will be soon. Setup puppet, monitoring, replication and provision them in order to get them ready to replace the older pc1004,5,6 and pc2004,5,6.
While rearchitecturing would be nice (T133523), it is out of scope due (unless minor trivial things that can be easily done) to the hard deadline, and a 1:1 replacement is more likely to happen until more time is available for that.
Due to extended disk available, emergency measures taken at T167784 can now be reverted (https://gerrit.wikimedia.org/r/#/c/operations/puppet/+/361656/)
