Â Well I’ve had the joy of doing a few of these so will share my experiences on how to get to the other side with minimum pain.Â I’m just going to blog here about email ….. otherwise it would be far too long a post.Â So here are some considerations:
- Attachments are compressed by default in Domino.Â Using Huffman compression in release 4 and 5 and if enabled LZ1 compression in Domino 6 and above.Â This means that unless you have a third party compression tool doing similar in Exchange you will see an expansion factor of anything between 10 and 40% per attachment, my experience tells me to make sure for every 1 MB of data in Notes that there is 1.3 MB available in Exchange.
- When you first migrate data the single instance does not work, so 1 email in Notes migrated to exchange = 1 email even if it has multiple recipients.Â Single instance only operates for new emails once your users are running on Exchange.
- What data are you going to migrate?Â Email, calendar, to do, personal address books, archived emails, personal journals….
- Where is the data?Â If it is local to a user how do you manage the migration.
- What tools and software do I need to deploy?
- What level of co-existence do I need while both email environments are running?Â none, email only, directory syncrhonisation, calendar and free time lookups – each adds complexity
- When I’m migrating users are there any limitations which will cap the number of people I can move at once?Â directory infrastructure, network bandwidth, number of migration stations, storage…..and many more
Well hopefully that will help a few people ensure they don’t miss huge chunks of work!!!!
