The telus email account on google is limited to email only so does not have access to all the other things you use with your google id - (groups, YouTube, blogger, etc).
I was migrated last year. I am the owner of a google group, so I was affected. I noticed before the migration (from blogger) that my google id had morphed into a new temporary name. The format is telus_name%telus.net@gtempaccount.com where telus_name is your telus email id. This is done in the Google universe so that your new Telus.net email account does not conflict with your original telus.net google id when your telus email account is migrated to gmail. The telus.net name was an alias prior to the migration, so I could still logon to Google functions. I went into my google group and added my telus email id as a second google group member prior to the migration.
I forget the exact steps I took before and during the migration to create and merge accounts. I now have a gmail.com email id and that is my main google id to access google apps. My google logon shows both accounts, and I can log onto either to access gmail. My gmail.com id has my original join date in my google group. My gmail.com id is a separate account for gmail and it works for other google functions. Somehow during the migration, my temp account was associated to my new google.com id. I have 2 separate gmail accounts, my converted telus.net account, and my new gmail.com account.
Sorry for the long explanation. The useful information is that your google id may still exist as the temporary gtempaccount.com id described above. You might be able to log into google with this id, and access your google apps. Not sure if you can assign this old google id to a new gmail.com google account to keep your app personal data intact. If not, then the other option is to create a separate, brand new gmail.com id to access google apps.
Good Luck
