how to resovle "'Subtask CheckPrereqs execution failed: Check Tenant Prerequisites Deserialization fails due to one SerializationException" error

I have hybrid environment with Exchange server 2013 CU8 and Office 365. Every thing was working fine but in coming few days public SSL was getting expired. so after renewing the public SSL on the on premise servers, i start rerunning the hybrid configuration wizard as the old certificate was used in it.
But while rerunning the hybrid configuration wizard from the on premises ECP i got the following error.
After looking it more on the internet i came to know that i should download  the latest Hybrid Configuration Wizard  available on ("http://aka.ms/TAPHCW"). after trying this new tool the wizard was completed without this error. 

The wizard did not complete successfully. Please see the list below for error details.

Storage drive appearing as RAW in Windows Server 2008 R2

I faced an issue that a storage drive assigned from DS 3400 was appearing in RAW format.
i was unable to open it, initialize it and it asking every time to format it. as it was not in NTFS format and Windows was unable to open it, RAW format was unknown for it.

Actually the was that, the server was restarted and the IQN was changed of the server due to some issue.
after putting the IQN again in Storage issue was resolved.

The IQN of a server you can find as below.
Open ISCSI initiator and then go to Favorite Targets and there you will see the IQN.

The IQN you will put in below path on the DS3400 storage.
Open DS3400 storage console (i have IBM DS storage Manager 10)--> here you have to open the required storage, -->Host Mappings Tab-->select the required host group--->right click on Drive and select-->select Manage host port Identifiers-->Add Host port identifier information (This value and the value on server should be the same)


P.S: possibility of this is

if you rename the server.
if you change the IP.
if there is network device between SAN and Server which malfunction.

The UMMailboxPolicy policy assigned to the mailbox in the source forest couldn‎'t be mapped to the policy in the target forest

I have hybrid environment with Exchange server 2013 and office 365. i was trying to migrate a mailbox from on premises to office 365. but was getting the following error and migration was failing.
the reason was that the user was enabled for UM and a UM policy was applying on it, which was not exist in office 365. so as a work around i just went to exchange control panel, search this user mailbox and disable the Unified Messaging in Phone and Voice Features, in mailbox feature of this user.
then tried to migrate again and was able to migrate this time.

WSUS service stoping again and again after each few minutes and administration console not connecting

I had WSUS server installed on the same server as SCCM primary server.
My issues

1. WSUS was not stable, it crashed again after few minutes
2. WSUS administration console did not connect
3.  In SCCM console the status of Software update point was not healthy

After searching enough i got the following link (https://blogs.technet.microsoft.com/wsus/2016/05/05/the-long-term-fix-for-kb3148812-issues/)
which is relevant to this issue but in my case KB3148812 was not installed and the KB3159706 was installed.
Now to resolve this issue i took the following steps

1. Deleting the wsus file from (C:\user\username\AppData\Roaming\Microsoft\MMC)
2. Uninstalling KB3159706
3. Restarting the server

 my issue was resolved.
