IRF configuration not working after switch replacement

[Syncorp12]

Good day,

I have done this before, replacing a switch in an IRF stack using these instructions:
https://support.hpe.com/hpsc/doc/public/display?docId=mmr_sf-EN_US000005537

Everything looks good although upon boot up I see the IRF ports come up and then go back down again.
New switch:

%Apr 26 12:02:04:666 2000 HP IFNET/3/LINK_UPDOWN: Ten-GigabitEthernet2/0/51 link status is UP.
%Apr 26 12:02:04:666 2000 HP IFNET/3/LINK_UPDOWN: Ten-GigabitEthernet2/0/52 link status is UP.
%Apr 26 12:02:04:666 2000 HP IFNET/3/LINK_UPDOWN: Aux0/0/0 link status is UP.
%Apr 26 12:02:04:667 2000 HP DEVM/5/FAN_RECOVERED: Fan 3 recovered.
%Apr 26 12:02:04:667 2000 HP DEVM/5/POWER_RECOVERED: Power PSU recovered.
%Apr 26 12:02:04:667 2000 HP DEVM/5/RPS_NORMAL: RPS 3 is normal.
%Apr 26 12:02:17:148 2000 HP SHELL/5/SHELL_LOGIN: Console logged in from aux1.
%Apr 26 12:02:19:370 2000 HP OPTMOD/4/MODULE_IN:
Ten-GigabitEthernet2/0/51: The transceiver is STACK_SFP_PLUS.

%Apr 26 12:02:19:538 2000 HP OPTMOD/4/MODULE_IN:
Ten-GigabitEthernet2/0/52: The transceiver is STACK_SFP_PLUS.

Existing stack:
%Jan 21 17:05:23:151 2019 MU-IRF-224 IFNET/3/LINK_UPDOWN: Ten-GigabitEthernet3/0/52 link status is UP.
%Jan 21 17:05:23:232 2019 MU-IRF-224 STM/6/STM_LINK_STATUS_UP: -Slot=3;
IRF port 2 is up.
%Jan 21 17:05:23:771 2019 MU-IRF-224 IFNET/3/LINK_UPDOWN: Ten-GigabitEthernet1/0/51 link status is UP.
%Jan 21 17:05:23:933 2019 MU-IRF-224 STM/6/STM_LINK_STATUS_UP:
IRF port 1 is up.
%Jan 21 17:05:23:970 2019 MU-IRF-224 STM/3/STM_LINK_STATUS_DOWN: -Slot=3;
IRF port 2 is down.
%Jan 21 17:05:24:301 2019 MU-IRF-224 STM/3/STM_LINK_STATUS_DOWN:
IRF port 1 is down.

Configuration of new switch:
interface Ten-GigabitEthernet2/0/51
#
interface Ten-GigabitEthernet2/0/52
#
irf-port 2/1
port group interface Ten-GigabitEthernet2/0/51 mode enhanced
#
irf-port 2/2
port group interface Ten-GigabitEthernet2/0/52 mode enhanced

Apparently the cables were crossed when reconnected. I updated the IRF configuration assigning te2/0/51 to irf-port 2/2 and vise-versa and the switch joined the stack after reboot.

Glad to know that switches has joined again into IRF.
