Migration terms help

I need help in the migration few questions I asked in last question. Actually I am aware of the terms however still need advance knowledge. Please do give examples, also please provide your own language answers not the bookish one.

http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/Q_26986639.html#a35499868

/////////////////////////////////

I know have to follow the wizard to install roles However I am having issues in understanding ' Install Client Access and Hub Transport server at location with HTTPS & SMTP entry points.'  Please tell me the HTTPS and SMTP entry point how to Install.  One more thing ' re-configure existing OWA  A record for new public IP and forward port 443 to the new Client Access Servier'. These two things arise the difficulty. Actually I was unable to understand SMTP flow, HTTP/HTTPS flow in and out. Therefore even I did not inquire a lot from the organisation. I think the speed that site links are using is also the cause of concern, please tell how to find it.

You don't seem to want to listen to the advice you are being given!

>>HTTPS & SMTP entry points

the point at which SMTP and HTTPS come in to your exchange Organisation.

As I have said numerous times in your previous questions without knowing A LOT more information about your setup it's impossible to provide you with an accurate proposal.  And since you seem reluctant to help us, it's not suprising that we are reluctant to help you.

Oh dematzer thanks please also help with
re-configure existing OWA  A record for new public IP and forward port 443 to the new Client Access Servier'. These two things arise the difficulty.

In your external DNS there will be an A record something like mail.domainname.com which is used for Outlook Web Access on HTTPS port 443. This will need to be reconfigured for the second Public IP address which is essential for an Exchange2003 to 2010 migration.

You need to reconfigure this.  I cannot be more specific than that!

If you don't understand these basic terms you really should not be putting a proposal together for any migration.  Let alone one that spans 10 sites and has 10,000 mailboxes

ok that is great I understood you said there fore reconfiguring it will be just the same no changes. Fine also speed that site links are using is also the cause of concern, please tell how to find it. I shall open a new question about quest and binary soon. Is there any of your many pages research work that you shall like to present to the coming generation for becoming expert like you in migration.

The speed of the site links won't cause a problem if they are not causing a problem now.  Exchange 2010 has no more overhead than 2003.

The speed you will need to ask the provider/client.

>>>Is there any of your many pages research work that you shall like to present to the coming generation for becoming expert like you in migration.

All of my migration guides are available freely here on Experts Exchange (you will see a list of my articles on my profile page) or on my blog.

Becoming an expert in migrations of any type involves many facets, some of which I have listed below:

-> understanding the source system
-> understanding the target system
-> understanding the impact of the migration on other systems in the network.
-> understanding the customer requirements
-> planning for the migration and if at all possible test it.
-> probably the most important understand your limits - don't commit yourself to something you cannot achieve.  No amount if cash is worth the amount of stress you will go through if you get yourself in too deep.  Not to mention what could happen if it all goes wrong and the company sack/sue you.

I have turned down projects that I don't understand.  I communicate with my customer.  If they know I don't know how to do what they want then I am not making promises I cannot keep.  Some clients may even pay for you to learn or be willing to wait for you to build a lab and test their scenario so you can learn it.

It is my opinion that you are in too deep, 10,000 mailbox migrations spanning 10 sites is a huge project and one even me as a consultant would hire in extra help on.

I sincerely hope you have some serious professional liability insurance in place.

You really need to read some of the guides like this one. Read them several times  and research any steps that you don't fully understand

and this one regarding dns configuration for legacy coexistance:

There is some good doco in MS technet and of course demazter's articles and blog...

e.g. you mentioned Lotus in one of the other threads : http://technet.microsoft.com/en-us/library/bb124161(EXCHG.65).aspx

Look at the left hand side panel for a list of topics, there is a lot of material there. You do need to do a lot of research and reading to decide if your knowledge is sufficient to undertake such a task. Not so much of a problem if everything works very smoothly (still a huge job and definitely not for the feint hearted) but more importantly if your knowledge extends to trouble shooting and contingency if something goes wrong (or not quite as the book says it should happen).

So, read, read, read, then decide. The link above is not such a bad process for any migration (not just notes) whilst some steps are unneccessary if upgrading, there are some good topics in there regardless.

Then look at some of the tech articles : http://technet.microsoft.com/en-us/library/bb187471(EXCHG.80).aspx if coming from 2003 you will want to read a few of the 2007 articles first - they explain new security paradigms and such like (including an interesting little article about "a day in the life of an exchange admin"), then continue on with exchange 2010 tech articles and whitepapers - such as : http://technet.microsoft.com/en-us/library/gg513523.aspx which should also give you a bit more insight into the types of detail you need to fully understand, or at least be able to gather before you begin.

Not a small question by any means

Just to echo demazter, it is not the type of exercise you enter into lightly and best to enlist the services of qualified experts to help design and then to help execute the migration.
