Pre-requisites for SMS to MDS Migration ?
Hello Experts,
I`m planning to perform an SMS to MDS Migration. Both SMS and MDS are on R81.10. What are the pre-requisites that need to be followed in terms of
1. Memory - ?
2. No. of cores - ?
3. Hard Disk. -- I looked at 'Installation & Upgrade Guide R81.10 ' and it says we need atleast 5 times size of sms export file on MDS. So on MDS which part of the file system we need at least 5 times ? Is it referring to /var/log ? or / or /boot or /dev/shm ?
Appreciate your responses!
Below are the customer specs :
MDS Hardware Specifications:
Memory – 32 GB
Cores – 16
Hard Disk -3 TB(95% used-var/log)
SMS Hardware Specifications:
Memory – 16 GB
Cores - 12
Hard Disk – 530 GB(85% used-var/log)

That is referring to the system partition /
By default, migrate_server will not keep the old logs or indices if not specified using
'-l' Export/import logs without log indexes.
'-x' Export/import logs with log indexes.
Note: Only closed logs are exported/imported.

@G_W_Albrecht So just to conform you are referring to below right ?
[Expert@test:0]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg_splat-lv_current 32G 7.3G 25G 23% /
/dev/md0 291M 79M 198M 29% /boot
tmpfs 32G 5.4M 32G 1% /dev/shm
/dev/mapper/vg_splat-lv_log 150G 15G 136G 10% /var/log
Secondly, does below need to be changed on MDS ?
1. Memory - ?
2. No. of cores - ?

Most customers using MDS deploy on VM - this is great for backup purposes and you can change CPU, RAM and HD space as needed. But if you want to use the current MDS HW mentioned above, i would look into past performance figures of current number of domains and estimate how many percent load will be higher when adding another domain.
sk104848 gives: For Multi-Domain Security Management Server, plan to allocate 6 GB for the base installation plus 2 GB for each additional Domain. Consider reserving 50% of the memory allocated and consider increasing the Virtual Machine's resource shares allocation.
16 Cores should be alright...
