[@prassanna6521]

WOW!Excellent video and gain lot of knowledge on from this thank you,can you please upload a video about migration troobleshooting also that helps a a lot for everyone...

[@JopDiengdoh]

Regardless of what your Microsoft 365 / Office 365 plan is, you need to buy licenses from Microsoft to run a cross-tenant migration natively. You'll need as many Cross Tenant User Data Migration add-on licenses as the number of users you want to migrate.

[@santhoshshashi303]

Thank you sharing the video. Today i learnt new things. ❤

[@nobody-P]

Such an extraordinary explanation... THank you, Sir...

[@Nawinsana]

Thank you Sir! The video was well explained. Please make more vides on Exchange, Onedrive, Sharepoint Migration

Thank you.

[@Chalamusafir]

At 9:31 -- used the wrong syntax due to which any other preexisting proxyaddress got removed. at 9:59 and 11:03 LEDN is not showing as updated coz LEDN from source is added as Proxy to Target Mailuser. Let me know if I am wrong or missed something Just learning

[@ChandanKumar-hg3eq]

Excelent explanation. Thank you! Please suggest can we use this method for migration of single domain users from one tenant to another.

[@funislife1]

Very good video and very useful. Thanks for your wonderful information it will help lots of engineers to upskills their migration knowledge. Can you please also suggest how to do migration for OneDrive and Teams data ❤❤

[@KaizenX7]

Hi. Thank you but i have this problem. When you created the mailuser on the new tenant, the user get no mailbox. How do i convert the mail user to a normal user ?

[@DevOffice365]

Thanks for information mate👏👏👏👏

[@Office365Concepts]

Any time! Thanks for watching.

[@frankmvabaza]

The best explanation. Thank you. Can you migrate active users while working? When the migration is complete, do you still have to configure the mailbox? How many mailboxes are you allowed to migrate across?

[@farid6448]

Great session, thank you.

[@edtan9761]

so user friendly!

[@adalidaborip1726]

There is a reason I can't see "Migration" in my Microsoft365 admin center menu?

[@YahkoobAyappally]

I believe there is small mistake in the script running in Source Tenant. If we are creating mail enabled security group manually, then no need to include the script new-distributiongroup command line. It’s repeating the step

[@SanthoshKumar-tn6tu]

Hi, Thank you for the detailed info. Is there any seperate add-on license required to perform this migration along with E3..or else just E3 license sufficient at both source and destination side??

[@soumyakantighosh2717]

as of now, Microsoft is providing this add license in every license type. So you can just select any license for the migration type

[@tushargade2242]

Please make video on migration from exchange server 2010/2013 to exchange server 2016/2019 with all types like cutover/stagged/ imap (if used)/ or any other type can be used

Hello Sir.. Does this migration included SharePoint , Teams and etc? I actually sourcing out how to do tenant to tenant migration .

[@srikanthsatyanarayana4457]

Hi, i just followed exactly the way you explained, however the batch completed with error, and it is because of the licence issue even after assigning the licence in both source and Target domain.

[@Timmy-Hi5]

excelent 😄

[@Office365Concepts]

Thank you.

Hey @Office365Concepts, at 9:30 to 11:00, your two LEDNs did NOT update. They don't update when I tried that command on my system, too.

Hi, is this Cross tenant migration which you have experienced wull that migrate the calendar , contacts and task? Please let me know thank you for the very good informative video

[@Office365Concepts]

Yes you can migrate emails, contacts and tasks in cross tenant migration.

[@prabu5113]

From where you got that link, can explain all steps, it can be easy to understand, now its little tough

[@PaoloGualano-ei7ni]

Hi, the video is very nice. One question, please. When we assign the license to the target MailUser, the mailbox creation process is not completed. It goes on and on. Do you have any suggestions or a way, or command, to understand what is happening to the destination mailbox? We have already configured the two properties before assigning the licenses.

[@pawankhunger275]

Thanks. This is a wonderful explanation and I love the work you do. I have a question here, if I’ve 1000 users to migrate. So do I need to set legacyexchange and exchange guid for all of them?? Or is there any other way of doing it either by PS or GUI?

[@Office365Concepts]

You can use PowerShell script to export and import these values for multiple users.

[@user-gw2wp5dn3p]

@@PrabakaranRaju-nk4vt This much something you are expected to do without any help as you are doing Migration of 1000 users.

[@FSCadmin]

hi thanks for this video, very helpful! , at 11:01 you say that both ExchangeGuid and LegacyExchangeDN were updated but the LegacyExchangeDN is the same as before. Is this normal? I am asking because I tried to do run the same commands and I got the same result as in your video. What happens if LegacyExchangeDN is not updated to match the source? Thanks!

[@late510]

Did you ever figure this out? When running "set-mailuser -identity "xxxxx" -exchangeguid "xxxxx" -emailaddresses "x500:xxxxx", I get the same warning message about Windows Live ID and the LEDN is not updated when I check to verify with the get-mailuser command

[@FSCadmin]

@@late510 in the end i gave up the idea of a manual migration and used a 3rd-party tool that made my life much easier! The issue with MS was that they require an enterprise license for this type of migration, which we don't have or need. I ended up using MigrationWiz from BitTitan, the cost was WAY LOWER than MS and most of the tasks were automated. I would recommend you MigrationWiz if it's an option. Good luck!

[@62128Kevin]

Thanks to share this ! It will migrate mailbox including contact/meeting ?

[@bikramjitsingh007]

it will migrate one drive as well of the user and what about sharepoint

[@zubinbalsara8414]

HI there, thanks for sharing such a great video. In our case we want migrate users, but the users have already got a mailbox (not mailuser) created on the target tenant, and they do get emails on the target mailbox. Our goal now is to completely migrate the source mailbox and just keep a redirect on source mailbox to the target mailbox so that any odd emails that make it to the source dont get lost but get redirected to target. HOw would do that kind of migration? Is this method still applicable?

[@Office365Concepts]

Hi Zubin, you can configure Exchange Hybrid migration. If you are not using Exchange server, then you can create a mail flow rule at the source to redirect emails to target tenant. Please refer to below videos: kzbin.info/www/bejne/ooaYknZ8i7dslc0 kzbin.info/www/bejne/g4izhKipqp2YrM0 kzbin.info/www/bejne/o4mVYpWXpJeebrc

What happends to the One Drive Content for the users migrated?

[@alexb7370]

Hello @Office365Concepts! I have 2 mailboxes to migrate from one tenant to another and after performing the migration it gave me errors on both mailboxes stating that "A Cross-tenant User Data Migration license is required to move a mailbox between tenants." .... Have you ever heard about something like this? I tried to find it in the MS products, but apparently it's not there.

[@FSCadmin]

hey, did you ever resolve this? I think you need a migration license as add-on to your MS subscription, I think you need one for each user that is being migrated, if you contact your microsoft reseller you should be able to add it to your tenant. Did you complete your migration in the end? I'd love to know how it went as I am creating a strategy to migrate 4 users to a new tenant

[@alexb7370]

@@FSCadmin Actually we ended up moving the mailboxes manually by backing up and importing the content to the new mailboxes. It took some time, but it's free and simple. If you have less than 50 mail accounts to migrate, that would be the solution imho. We didn't migrate TEAMS or anything else except mailboxes content.

[@prasanthvarma9501]

Hi, While preparing source tenant, the script is creating a new security group, but you have already created the security group before manually and added the users right. Why are we creating a new security group again which doesn't have any users and scoping it to organization relationship? #Prepare Source tenant $targetTenantId="Tenant id of the Target Tenant" $appId="Migration Application ID" $scope="Name of the Security Group" New-DistributionGroup -Type Security -Name $scope $orgrels=Get-OrganizationRelationship $existingOrgRel = $orgrels | ?{$_.DomainNames -like $targetTenantId}
