Migrating to exchange 2013 has been a nightmare compared to migrating to 2010 from 2003.
Here's my problem. After a successful migration from exchange 2003 to 2010 start the next migration to 2013. Successfully installed all aspects of 2013 and it is up to date on all patches/rollups etc.
So started testing. Migrated a test mailbox to the new database, worked great. First problem was I could receive email but not send to either internal or external address. After a long search found that several of my services wouldn't start upon a startup/reboot of server which is still an issue. After manually starting services was able to send email successfully. Great next test. Move a live mailbox. so I attempted to move my mailbox. No joy it just sits there in syncing (over 24 hours). Stopped migration, no problem. Attempted again using a higher baditem count etc. same results. Hmmmmm, tried two other test mailboxes. Same results.
What I've done so far; Search, Search and more searching and not finding much in what to check for.
Trying to get this rolled out by EOY bu that's not looking like it's going to happen.
